Yep, just a couple of cherry-picks. Good test coverage and some docs 
already included for 17748.  Happy to put that on my plate if you're 
good with it. I can reasonably assume that no one is against it :)

I think I had knocked out docs for the "phase 1" stuff before we merged 
it in from the original feature branch. I'll double check and update the 
gdoc. Perhaps this was just a timing thing.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

In another thread in this list I flag the coming 2.0.0-beta-2. Look for an
RC in the next day or so.

After 2.0.0-beta-2 makes it out, I'll cut branch-2.0. Soon after will come
our first hbase-2.0.0 release candidate. Expect this within a week or so
after beta-2 after remaining blockers are addressed (At this stage,
blockers are mostly documentation). Scream if there is something that has
to make 2.0.0 that I may have missed, but at this point, only critical
bug-fixes or compatibility breakages will be entertained.

I just did a pass over the issues filed against hbase-2.0.0. I did a pretty
brutal edit, sparse on commentary mostly because the count of issues
against 2.0.0 was high. There were a fair amount filed against '2.0.0' just
because 2.0.0 used to be thought of as the end of the rainbow, an event
that was way off on the horizon that would never arrive[1]. I unscheduled
the bulk of these. Reschedule against 2.0.0 if I got it wrong.  A good
bunch were great ideas almost- or half-done or never started (HBASE-14055
RegionServer Refactor, HBASE-15531 Favored Nodes, Andy's security
improvements, etc.). These were also unscheduled. Others that were really
old without recent updates I resolved. A few had been realized via other
channels.

Here is the current list [2]. Help on blockers would be much appreciated.

Your 2.0.0RM

P.S.No scale testing, perf compare, compatibility, or exercise of new
features (at least to my knowledge) has been done. We could do with some
exercise along any of these dimensions if any of you have a few spare
cycles. Thanks.

1. hbase-2.0.0 still has this smell to it, but we do our best.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

Heads-up, I'm working on cutting a beta-1. Shout if there is something you
think needs to make it in (The Chia-Ping Tsai cleanups look good). I'm
mainly waiting on the hbase-thirdparty changes to go in. The rest can wait
it.

Thanks,
S

Ram, Chia-Ping Tsai, and Anoop are doing a nice job here and it should be
done in next day or so.

Chatted with Anoop and Ram. Because it is so late in the day and because it
critical that the user have a good experience out of the box -- which
requires time and testing -- we are going to punt this from 2.0. Will look
at it for 2.1 (or 3.0 if soon). 2.0 will still be carrying all of the boys
offheap read/write path goodness.

Good progress here. In perf testing asyncfswal makes us generally faster.
Duo making good progress on last few tests that are in the way of our
making this default for hbase2.

A load of goodness has been landing these last few weeks. Keep up the great
work.

Your hbase-2 RM.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

Update on hbase-2.0.0-beta-1. I'm going to put up a beta-1 RC before
Christmas day.

Here is the list [1]. We're doing pretty good. We've fixed a load since the
last update including some nice cleanups  two weeks ago (e.g. undoing
client dependency on curator/zk watching making the dependence read-only)
but there are still a few hairy ones hanging out there.

 * HBASE-18946 Stochastic load balancer assigns replica regions to the same
RS
   This one is proving a little tough. Ram has been banging his head on it.
We'll be able to clear a bunch of test failures once this is done.

 * HBASE-19112 Suspect methods on Cell to be deprecated
   Good discussion up on the JIRA. We need to be crystal clear around Cell
and derivatives API and Audience when we ship 2.0.

 * HBASE-17204 Make L2 off heap cache default ON
   We need to try this at least so offheaping can be default.

Making asyncfswal default is also ongoing, HBASE-16890
<https://issues.apache.org/jira/browse/HBASE-16890>, making good progress.

I punted HBASE-19147 "All branch-2 unit tests pass" out to beta-2. Our unit
test story has gotten better and a few of us are actively working on
flakies [2] but we may make a beta-1 w/o shutting down all failures.

Speak up if you need help on an issue or if you think we are missing items
from our list.

Thanks for all the hard work,

The hbase-2.0.0 RM.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

hbase-2.0.0-beta-1 update (Reminder, beta-1 is where we finish last
remaining features and apply final polish to API. There will be a beta-2
but it is about upgrade/rolling-upgrade and bug fixes ONLY).

Myself and Mr. Drob did a pass over the outstanding hbase-2.0.0-beta-1 list
this morning. See here [1].

There are about ~12 issues in progress with most of these about to land.
There are 37 TODO. Many of these are tests we need to run, some are related
to the backup/restore, but a good few are meaty w/o assignees.

The awkward outstanding ones as I see it are the below:

HBASE-18946 Stochastic load balancer assigns replica regions to the same RS
HBASE-17204 Make L2 off heap cache default ON
HBASE-19112 Suspect methods on Cell to be deprecated
HBASE-19147 All branch-2 unit tests pass

We need to make progress on the above or punt on them (can't punt on the
last one though).

Any ideas on what configs we should update in hbase2? Dump ideas into:
HBASE-19148 Edit of default configuration

Still hoping for an early December beta-1 RC. beta-2 hopefully will be
close behind.

Comments? Thoughts?

Thanks all,
S

Re: Moving 2.0 forward

[Mike Drob <md...@apache.org>]

Hoping to keep momentum going from our Stack working on alpha4, I tried to
take a stab at triaging some of the open beta-1 issues.

I moved some docs stuff out form beta-1 to 2.0-GA, if it gets done sooner
then I'm happy to see it pulled back in. Trying to balance optimism with
realism here, and knowing that documentation unfortunately often gets
pushed to the back-burner.

Also, I poked some folks on unassigned issues that they've filed for
beta-1, especially in the last few days. If issues don't have an owner they
are unlikely to get worked. I chatted with stack and he agreed to take on
some of the tasks, but there's a lot of surface area to cover.

If you you're working on issues that are critical for beta-1, please mark
them as such. Then the rest of the community will know to help prioritize
feedback and reviews there.

Do we have a general theme for the betas like we did with the alphas?

Beta1 is upgrades work from branch1, beta2 is rolling upgrades work as
well? Continue to work on tests throughout?

Mike

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

I want to push an alpha-4 today. A few items didn't make it (HBASE-19092).
They need more time. We'll pull them in for beta-1. CP API is basically
done. There may be some changes for beta-1 but hopefully only changes
informed by experience trying to port an existing Coprocessor to hbase2.

Shout if there is anything that needs to make alpha-4.

Thanks,
St.Ack

Yup, that was going to be my plan, Mike!

Making a pass now, and will check back later tonight again. I see others 
have already done some work today on this front.

Re: Moving 2.0 forward

[Mike Drob <md...@apache.org>]

Josh - Do you want to kick off a bunch of QA runs? (Do you know how to do
it directly on the jenkins job, so you don't have to bother with JIRA
uploads)

If you're busy, then I can make time tomorrow or Sunday to kick off jobs,
but I want to make sure we're not duplicating effort and jenkins cycles.

Re: Moving 2.0 forward

[Josh Elser <el...@apache.org>]

My turn to bump ;)

By my take: HBASE-18770 and HBASE-19092 are the only issues that remain 
needing some more work. The rest are just awaiting a good QA run.

Unless I hear otherwise, I'll try to keep an eye on things over the 
weekend, bump them along as necessary, and get them committed. Would be 
great to be able get a vote up on Monday.

Got it. Thanks for you explanation.

When you think you'd be done w/ the sync of Admin and AsyncAdmin
> Interfaces? Are the changes to Admin or to AsyncAdmin?

There are two issues (HBASE-19009 and HBASE-18950) need more review.  After
resolve these issues, I will upload a new patch for HBASE-18911. Thanks.

Yeah, we were supposed to be done w/ public API changes when we shipped
alpha-3 (smile).

For Admin Interface, semantic versioning applies as per Duo comment. I see
some polish still being done on the Admin/Table APIs (removal of deprecated
methods, alignment of Admin and AsyncAdmin APIs). Hard to say no to this
clean up on our most public facing Interfaces.

When you think you'd be done w/ the sync of Admin and AsyncAdmin
Interfaces? Are the changes to Admin or to AsyncAdmin?

Thank you Guanghao Zhang,

Re: Moving 2.0 forward

["张铎 (Duo Zhang)" <pa...@gmail.com>]

Alpha4 aims to freeze the CP related API, not the public API. We break
everything for CP so we need to push out a stable(I hope) version to let CP
users learn how to implement their project on top of the new APIs.

For public API we have rules on how to keep compatible so I think it is
less hurt for users, beta1 is fine.

Re: Moving 2.0 forward

[Guanghao Zhang <zg...@gmail.com>]

I saw beta == no new features, no API changes, just fixes. And I am working
on HBASE-18805 to unify Admin and AsyncAdmin methods. The fix version was
2.0-beta-1. But I thought this will introduce API change(deprecate some API
and introduce new one). So should I change the fix versions to 2.0-alpha-4
and finish it before we release 2.0-alpha-4?

Issue HBASE-18978 (Align the methods in Table and AsyncTable) may have same
problem. Thanks.

Re: Moving 2.0 forward

["张铎 (Duo Zhang)" <pa...@gmail.com>]

OK, skimmed,  we are in trouble! The in memory compaction just use the same
constructor with normal compaction to construct a StoreScanner, and use it
to do compaction...

We have to provide several preXXX and postXXX for it, at least we should
allow user reset TTL and max versions, and also do filtering on the scanner.

Thanks.

Re: Moving 2.0 forward

["张铎 (Duo Zhang)" <pa...@gmail.com>]

When adding back the pre(Flush/Compact/Store)ScannerOpen methods in
HBASE-19033, I found that there maybe a hole in our CP hools. It is the in
memory compaction.

As Anoop suggested in HBASE-19001, we still need to give user the ability
to extend the max versions and TTL config, so I plan to add back the hooks
above to let CP users can change the max versions and TTL of a ScanInfo
object. But I'm not sure whether in memory compaction will also discard
expired cells, if so then we are in trouble...

Thanks.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

Chatting with my coworker Mr. Mike Drob, we were batting back and forth
what remains to be done. Surfacing our thoughts here so you all clued
in....Or if you think otherwise, please speak up.

We have ~13 issues to land:
https://issues.apache.org/jira/projects/HBASE/versions/12341594 About two
are meta-issues that are about process which leaves 11.

Duo and Zheng Hu are to merge the FilterList fixes improvements
(HBASE-19057, HBASE-18410 et al.). These are blocker because some changed
API/semantic that we need to get out earlier rather than later.

Once the above is merged, HBASE-13346, change of Filter method names to
mention Cell instead of KeyValue can land.

HBASE-199048 needs a review (Anoop will probably do it), removing
IA.Private objects as params to MasterObserver... Hopefully this goes in
soon.

Duo is hard at work on trackers for flush and compaction for CPs
(HBASE-18905). How is HBASE-19033 looking Duo (facility for Tephra)?

I think HBASE-18906 (Phoenix Region#waitFor...) will evaporate after Duo is
done w/ his work above.

I'm on HBASE-18770 bypass and HBASE-19077 restore some parity after all the
purges allowing CPs do direct calls against Regions in same Host.

Anoop is on HBASE-19047 (Fixes) and Ram on cleanup of CellUtil.

Another day or two?

St.Ack

Re: Moving 2.0 forward

[ramkrishna vasudevan <ra...@gmail.com>]

Hi Stack

Do you want HBASE-18995 before the alpha-4 (REmoving exposed internal APIs
from CellUtil)? Because you had mentioned no more API changes. If so I will
start making changes and put up a patch ASAP.

Regards
Ram

Thanks for the offer Josh. All items seem assigned and are being actively
worked on. If you get a moment, reviews by you (or anyone else) helps move
the process along.

We need to merge in HBASE-18410 branch to pick up Filter improvements. Then
HBASE-13346 can go in.

You are already helping out on HBASE-18906, thanks. Looks like that will be
addressed by other alpha-4s about to land.

I was trying to work on helping out on the outstanding alpha-4 stuff 
last week -- will be continuing to try to do the same this week.

If you need any help, Stack, or if others need reviews where I haven't 
noticed on my own: feel free to @mention me.

Re: Moving 2.0 forward

[Mike Drob <md...@apache.org>]

I went ahead and tagged those as tentatively 2.0.0-alpha3 in jira so that
we can have them all in one place later. Folks can move additional issues
in and out as they see appropriate.

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

(Reviving this thread)

Lets push out alpha-4 this week. Alpha-4 is the release that has the
refactor of the Coprocessor API shutting down access to internals marked
InterfaceAudience.Private.

The outstanding list is here:
https://issues.apache.org/jira/projects/HBASE/versions/12341594

Please push in anything marked alpha-4 that belongs to you.

If issue, talk out loud on this thread. If you need a review to land an
item, shout on the issue and here; we'll help you out.

As is, items are coming along nicely I'd say. We need to merge the filter
branch -- HBASE-18410 -- so APIs are finished for hbase2.

Post alpha-4, we'll have to hunt down our downstreamers and help them test
on top of alpha-4 so rolling into beta-1, we have confidence our
downstreamers know what to expect (or we discover what we missed BEFORE we
beta-1).

Thanks for time,
S

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

I'll put up an alpha3 RC Monday, probably Monday night. That should be
time, if we all sprint, for the public-facing API fixes to be done.

I had a bunch of Coprocessor refactor and fixup scheduled for alpha3 but it
is plain that more time is needed (in spite of valiant effort so far by
Anoop, Duo, Appy, etc.). Therefore, lets run a 2.0.0-alpha-4 whose theme is
"Coprocessor Fixup". Hopefully we can put an alpha-4 up by the following
week.

We should then be ready for beta (beta == no new features, no API changes,
just fixes).

Thanks,
St.Ack

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

I put up the hbase-2.0.0-alpha2 release candidate. Please vote on it.

For hbase-2.0.0-alpha3, the theme is solidifying API. I hope to get a
release out in the next week or so.

I did a weeding of 2.0.0 issues over the last day. If folks are interested
in helping out, below are the items I think we need done for alpha3 (below
are at least 'Critical' status, are API possibly altering items, and are
absent those JIRAs that are making active progress, i.e. the HTD/HCD revamp
by Chia-Ping Tsai). A project NOT listed that needs doing is what Andrew
did comparing 1.3. and 1.4 APIs

* HBASE-18622 Mitigate compatibility concerns between branch-1 and branch-2
This is to do what Andrew did between 1.3 and 1.4 branches only do it
between branch-1 and branch-2.

* HBASE-10462 Recategorize some of the client facing Public / Private
interfaces
This one is almost done. It could do with a finish, attention to the items
in last comment, and then our codebase could do with another sweep after
the spirit of this issue since a bunch has gone in since the pass that was
the basis of this issue.

* HBASE-10504 Define Replication Interface
I was going to take a crack at this as part of the revamp forced by
'HBASE-15982 Interface ReplicationEndpoint extends Guava's Service' but if
anyone else is interested, be my guest.

* HBASE-14996 Some more API cleanup for 2.0
Has a bunch of subtasks, some of which are being worked on. Needs finishing.

* HBASE-14998 Unify synchronous and asynchronous methods in Admin and
cleanup
Needs a pass. Small issue I think. Could also look at new AsyncClient and
make sure symmetry.

* HBASE-15607 Remove PB references from Admin for 2.0
Predicated on result of an ongoing DISCUSSION thread but needs to be done.

Rolling upgrade will have implications for our API. Would be good to try it
and figure what needs fixup (as said above, according to trial by Sean, we
might not be too bad here):
* HBASE-16060 1.x clients cannot access table state talking to 2.0 cluster
* HBASE-16550 Procedure v2 - Add AM compatibility for 2.x Master and 1.x
RSs; i.e. support Rolling Upgrade from hbase-1 to -2.

* HBASE-17442 Move most of the replication related classes to hbase-server
package
The above would be good to do generally but it may make for ripples in API
so would be good to do now.

* HBASE-18106 Redo ProcedureInfo and LockInfo
Balazs is working on this. The idea is that we avoid adding two new types
to our API, two types that are nought but curtailed, read-only views on
internals. Input if you have time appreciated.

* HBASE-18596 A hbase1 cluster should be able to replicate to a hbase2
cluster; verify
Esteban is looking at this one

* HBASE-9417 SecureBulkLoadEndpoint should be folded in core
* HBASE-17143 Scan improvement

Our Coprocessor Interface needs a tough edit. It exposes implementations
marked audience Private and returns implementations rather than Interfaces.
In a few locations, we allow returning an alternate implementation
altogether which is probably something we don't want a CP doing. To that
end, the following issues started by Duo and Anoop need to be taken to the
finish line; ideally they'd have an owner:

* HBASE-18169 Coprocessor fix and cleanup before 2.0.0 release <= The
umbrella issue.
* HBASE-18298 RegionServerServices Interface cleanup for CP expose
* HBASE-16769 Deprecate/remove PB references from MasterObserver and
RegionServerObserver


Nice-to-haves:

* HBASE-15284 Make TimeRange constructors IA.Private and remove unused
TimeRange constructors

* HBASE-10944 Remove all kv.getBuffer() and kv.getRow() references existing
in the code
This is the end of an old long-running project moving up on to Cell
Interface. We think it is done but for a few little items (deprecate KV
methods in MR and provide Cell versions instead...)

* HBASE-13271 Table#puts(List<Put>) operation is indeterminate; needs fixing

* HBASE-13346 Clean up Filter package for post 1.0

* HBASE-14255 Simplify Cell creation post 1.0
* HBASE-14997
Move compareOp and Comparators out of filter to client package

* HBASE-13740 Stop using Hadoop private interfaces

What about:

* HBASE-18601 Remove Htrace 3.2
As has been noted, the HTrace API is our 'trace' API.

If interested in any of the above and you need a legup, just ask in the
issue and I'll be by....

Thanks,
St.Ack

Re: Moving 2.0 forward

[Guanghao Zhang <zg...@gmail.com>]

About compatibility, there is one incompatible change about the replication
TableCFs' config. The old config is a string and it concatenate the list of
tables and column families in format "table1:cf1,cf2;table2:cfA,cfB" in
zookeeper for table-cf to replication peer mapping. When parse the config,
it use ":" to split the string. If table name includes namespace, it will
be wrong (See HBASE-11386
<https://issues.apache.org/jira/browse/HBASE-11386>). It is a problem since
we support namespace (0.98). So HBASE-11393
<https://issues.apache.org/jira/browse/HBASE-11393> (and HBASE-16653
<https://issues.apache.org/jira/browse/HBASE-16653>) changed it to a PB
object. When rolling update cluster, you need rolling master first. And the
master will try to translate the string config to a PB object. But there
are two problems.
1. Permission problem. The replication client can write the zookeeper
directly. So the znode may have different owner. And master may don't have
the write permission for the znode. It maybe failed to translate old
table-cfs string to new PB Object. See HBASE-16938
<https://issues.apache.org/jira/browse/HBASE-16938>
2. We usually keep compatibility between old client and new server. But the
old replication client may write a string config to znode directly. Then
the new server can't parse them.

PS: HBASE-11386 is a problem since 0.98. But there are not too many users
report this problem. So it maybe not a big incompatible issue......

Re: Moving 2.0 forward

[Stack <st...@duboce.net>]

Heads-up:

I'm about to put up an hbase-2.0.0-alpha2 Release Candidate. Theme is
updated dependencies, reliance on relocated popular libs (guava, netty,
protobuf), purge of checked-in generated src, and master-carries-no-regions
by default.

alpha3 I hope will follow soon after (end-of-August?). Its theme will be
settling the APIs and compatibility (At first blush, we are not looking too
bad; our Sean ran some tests over weekend that have hbase-1 client running
against an hbase-2 cluster....). The Coprocessor Interface revamp should be
done by alpha3 (i.e. returning Interfaces rather than Implementations, and
our shutdown of CPs accessing classes in hbase marked InterfaceAudience).
We'll also have purged thirdparty classes from our API; e.g. guava 0.12
Service showing through in our replication API and protobufs in Admin
Interface. On alpha3, we will have to do a bunch of outreach to make sure
our downstreamers are up on what is coming down the pipe.

Beta1 in mid-September?

I encourage you to check out the items marked for hbase2:
https://issues.apache.org/jira/projects/HBASE/versions/12327188 Edit as you
see appropriate. Punt if you know the JIRA will not get any attention in
next month or so.

A bunch of issues marked blocker are unassigned. I'll leave them as is
another while but I'll boot them soon.

While I have your attention:

+ I think we should leave thrift version at 0.9.3. Moving hbase thrift to
0.10.0 will break existing clients. The change is easy enough if folks need
to upgrade their hbase thrift. See HBASE-18591.
+ Upgrade from 0.94 is disallowed. You have to get to 1.0 first (0.98?).
