[ANNOUNCE] Apache HBase 1.0.0 is now available for download
The HBase Team is pleased to announce the immediate release of HBase 1.0.0.
Download it from your favorite Apache mirror [1] or maven repository.
HBase 1.0.0 is the next stable release, and the start of "semantic
versioned"
releases (See [2]).
The 1.0.0 release has three goals:
1) to lay a stable foundation for future 1.x releases;
2) to stabilize running HBase cluster and its clients; and
3) make versioning and compatibility dimensions explicit
Including previous (developer preview) 0.99.x releases, 1.0.0 contains over
1500
jiras resolved on top of 0.98.0. Some of the major changes are:
API reorganization and changes
HBase’s client level API has evolved over the years. To simplify the
semantics and to support and make it extensible and easier to use in
the future, we revisited the API before 1.0. To that end, 1.0.0 introduces
new APIs, and deprecates some of the commonly-used client side APIs
(HTableInterface, HTable and HBaseAdmin).
We advise to update your application to use the new style of APIs, since
deprecated APIs will be removed in future releases (2.x). See [3] and [4]
for an overview of changes.
All Client side API's are marked with InterfaceAudience.Public class,
indicating that the class/method is an official "client API" for HBase
(See “11.1.1. HBase API Surface” in the HBase Refguide[2] for more details
on the Audience annotations) Going forward, all 1.x releases are planned
to
be API compatible for classes annotated as client public.
Read availability using timeline consistent region replicas
This release contains Phase 1 items for experimental "Read availability
using
timeline consistent region replicas" feature. A region can be hosted in
multiple region servers in read-only mode. One of the replicas for the
region
will be primary, accepting writes, and other replicas will be sharing the
same
data files. Read requests can be done against any replica for the region
with
backup RPCs for high availability with timeline consistency guarantees.
More
information can be found at HBASE-10070.
Online config change and other forward ports from 0.89-fb branch
HBASE-12147 forward ported online config change which enables some of the
configuration from the server to be reloaded without restarting the region
servers.
Master runs a Region Server as well
Starting with 1.0.0, the HBase master server and backup master servers
will
also act as a region server. RPC port and info port for web UI is shared
for
the master and region server roles. Active master can host regions of
defined tables if configured (disabled by default). Backup masters will
not
host regions.
Other notable improvements in 1.0.0 are listed (but not limited to) below:
- A new web skin in time for 1.0 (http://hbase.apache.org)
- [HBASE-5349] - Automatic tuning of global memstore and block cache sizes

Compatibility
-----------------
Source Compatibility:
Client side code in HBase-1.0.0 is (mostly) source compatible with earlier
versions. Some minor API changes might be needed from the client side.
Wire Compatibility:
HBase-1.0.0 release is wire compatible with 0.98.x releases. Clients and
servers running in different versions as long as new features are not used
should be possible.
A rolling upgrade from 0.98.x clusters to 1.0.0 is supported as well. 1.0.0
introduces a new file format (hfile v3) that is enabled by default that
0.96.x code cannot read. Thus, rolling upgrade from 0.96 directly to 1.0.0
is
not supported.
1.0.0 is NOT wire compatible with earlier releases (0.94, etc).
Binary Compatibility:
Binary compatibility at the Java API layer with earlier versions (0.98.x,
0.96.x and 0.94.x) is NOT supported. You may have to recompile your client
code and any server side code (coprocessors, filters etc) referring to
hbase jars.
Upgrading
--------------
See [5] for upgrade instructions and extended discussion on the changes.
>From 0.98.x : Upgrade from 0.98.x in regular upgrade or rolling upgrade
fashion
is supported.
>From 0.96.x : Upgrade from 0.96.x is supported with a shutdown and restart
of
the cluster.
>From 0.94.x : Upgrade from 0.94.x is supported similar to upgrade from
0.94 -> 0.96. The upgrade script should be run to rewrite cluster level
metadata. See [6] for details.
Supported Hadoop versions
--------------------------------------
1.0.0 release drops support for Hadoop-1.x releases. Only Hadoop-2.x
releases are supported. Hadoop-2.4.x, Hadoop-2.5.x and Hadoop-2.6.x releases
are the most tested hadoop releases and we recommend running with those
or later versions. Earlier Hadoop-2 based releases, hadoop-2.2.x and 2.3.x
are not tested to the full extend. More information can be found at [8]
Supported Java versions
----------------------------------
1.0.0 release drops support for JDK6. Only JDK7 is supported. JDK8 support
is experimental. More information can be found at [9].
HBase-1.0.0 is marked as the current stable version, and we encourage all
users
to start using this version.
Thanks to everybody who contributed to this release!

Re: [ANNOUNCE] Apache HBase 1.0.0 is now available for download
Posted by "zhou_shuaifeng@sina.com" <zh...@sina.com>.
Great!
zhou_shuaifeng@sina.com
From: Enis Söztutar

Subject: [ANNOUNCE] Apache HBase 1.0.0 is now available for download
The HBase Team is pleased to announce the immediate release of HBase 1.0.0.
Download it from your favorite Apache mirror [1] or maven repository.
HBase 1.0.0 is the next stable release, and the start of "semantic
versioned"
releases (See [2]).
The 1.0.0 release has three goals:
1) to lay a stable foundation for future 1.x releases;
2) to stabilize running HBase cluster and its clients; and
3) make versioning and compatibility dimensions explicit
Including previous (developer preview) 0.99.x releases, 1.0.0 contains over
1500
jiras resolved on top of 0.98.0. Some of the major changes are:
API reorganization and changes
HBase’s client level API has evolved over the years. To simplify the
semantics and to support and make it extensible and easier to use in
the future, we revisited the API before 1.0. To that end, 1.0.0 introduces
new APIs, and deprecates some of the commonly-used client side APIs
(HTableInterface, HTable and HBaseAdmin).
We advise to update your application to use the new style of APIs, since
deprecated APIs will be removed in future releases (2.x). See [3] and [4]
for an overview of changes.
All Client side API's are marked with InterfaceAudience.Public class,
indicating that the class/method is an official "client API" for HBase
(See “11.1.1. HBase API Surface” in the HBase Refguide[2] for more details
on the Audience annotations) Going forward, all 1.x releases are planned
to
be API compatible for classes annotated as client public.
Read availability using timeline consistent region replicas
This release contains Phase 1 items for experimental "Read availability
using
timeline consistent region replicas" feature. A region can be hosted in
multiple region servers in read-only mode. One of the replicas for the
region
will be primary, accepting writes, and other replicas will be sharing the
same
data files. Read requests can be done against any replica for the region
with
backup RPCs for high availability with timeline consistency guarantees.
More
information can be found at HBASE-10070.
Online config change and other forward ports from 0.89-fb branch
HBASE-12147 forward ported online config change which enables some of the
configuration from the server to be reloaded without restarting the region
servers.
Master runs a Region Server as well
Starting with 1.0.0, the HBase master server and backup master servers
will
also act as a region server. RPC port and info port for web UI is shared
for
the master and region server roles. Active master can host regions of
defined tables if configured (disabled by default). Backup masters will
not
host regions.
Other notable improvements in 1.0.0 are listed (but not limited to) below:
- A new web skin in time for 1.0 (http://hbase.apache.org)
- [HBASE-5349] - Automatic tuning of global memstore and block cache sizes

Compatibility
-----------------
Source Compatibility:
Client side code in HBase-1.0.0 is (mostly) source compatible with earlier
versions. Some minor API changes might be needed from the client side.
Wire Compatibility:
HBase-1.0.0 release is wire compatible with 0.98.x releases. Clients and
servers running in different versions as long as new features are not used
should be possible.
A rolling upgrade from 0.98.x clusters to 1.0.0 is supported as well. 1.0.0
introduces a new file format (hfile v3) that is enabled by default that
0.96.x code cannot read. Thus, rolling upgrade from 0.96 directly to 1.0.0
is
not supported.
1.0.0 is NOT wire compatible with earlier releases (0.94, etc).
Binary Compatibility:
Binary compatibility at the Java API layer with earlier versions (0.98.x,
0.96.x and 0.94.x) is NOT supported. You may have to recompile your client
code and any server side code (coprocessors, filters etc) referring to
hbase jars.
Upgrading
--------------
See [5] for upgrade instructions and extended discussion on the changes.
From 0.98.x : Upgrade from 0.98.x in regular upgrade or rolling upgrade
fashion
is supported.
From 0.96.x : Upgrade from 0.96.x is supported with a shutdown and restart
of
the cluster.
From 0.94.x : Upgrade from 0.94.x is supported similar to upgrade from
0.94 -> 0.96. The upgrade script should be run to rewrite cluster level
metadata. See [6] for details.
Supported Hadoop versions
--------------------------------------
1.0.0 release drops support for Hadoop-1.x releases. Only Hadoop-2.x
releases are supported. Hadoop-2.4.x, Hadoop-2.5.x and Hadoop-2.6.x releases
are the most tested hadoop releases and we recommend running with those
or later versions. Earlier Hadoop-2 based releases, hadoop-2.2.x and 2.3.x
are not tested to the full extend. More information can be found at [8]
Supported Java versions
----------------------------------
1.0.0 release drops support for JDK6. Only JDK7 is supported. JDK8 support
is experimental. More information can be found at [9].
HBase-1.0.0 is marked as the current stable version, and we encourage all
users
to start using this version.
Thanks to everybody who contributed to this release!
