QA effort to support windows as a production platform

Hi All,

We will be using zookeeper quite extensively for clustering. Windows is one
of the platforms that we may need to support. Since Win32 is not supported
as a production platform I was wondering to what extent is zookeeper tested
on windows. We are also interested on using Zookeeper on Win64 platform. Is
Win64 supported? Are there any plans to support Win32/Win64 for production?
If not, what would one need to do support windows and what would be the
estimated QA effort?

Please advise. Thanks.

Regards,
-Vishal

Hi,

Any comments on the questions below?  Depending upon the QA effort required,
we will be happy to contribute as well. Please let me know.

There's probably some timing difference in the jvm or networking that's 
causing this to show up in windows vs unix. We shutdown the servers as 
part of the tests, as each server (quorum test) shuts down connectivity 
btw the servers will be lost, that's what this is showing.

Ok, great. I've slated 734 for 3.3.1/3.4.0. If you'd like to contribute 
a patch please feel free (you need to submit as an attachment rather 
than inlining in the desc, see this link for details):

3 distinct clusters you mean or 3 servers; 1 on windows and 2 on linux? 
(that would be a interesting test btw :-) )

Ben has been out of the office, once he gets back he's the best person 
to shed light. If you have specific questions someone else might be able 
to shed light in the mean time.

You might be underprovisioning the server(s)? Try monitoring the servers 
while running the test. You can use something like
http://github.com/phunt/zktop
esp the "min/avg/max latency" information.

My experience on windows is that the IO is not as good as unix (esp 
going through java). You should def. test under some load (using the 
latency tester as I mentioned earlier, simliar to my tests on the wiki) 
to ensure that the system will function in this environment. Ensure that 
you have enough heap, you might need to tune the GC to turn on 
cms/incremental GC (that could also be the issue you saw earlier), and 
also monitor the disk activity.

Btw, have you tested the 4 letter words? stat and such I mean. Would be 
good to verify as well as they are critical for monitoring the system 
once in production.

Great, happy to have them. See the how to contribute link above.

That will be great. Having an actual user who's running in production 
under that configuration would bring even more weight.

At some point we should look into the C client side of things as well. 
That will be harder, but if we can do it it would mean that 
python/perl/etc... would also be available for the platform.

Thanks!

Re: QA effort to support windows as a production platform

Posted by Vishal K <vi...@gmail.com>.
Hi Patrick,

So far I have done the following:

1. Ran junit tests on both windows and Linux. I ran into few issues with the
tests: https://issues.apache.org/jira/browse/ZOOKEEPER-734. Also, the path
to dataDir in zoo.cfg should be either UNIX-style path or should contain
double backslashes instead of one. I think the path compatiblity issue is
the only bug found so far. I was a big skeptical earlier about the junit
test results since the logs of the junit tests on Windows differ from that
on linux. But as you mentioned in your earlier reply it is probably
difference in networking libraries (I am using the same java version on
both).

2. Created a 1 Windows + 2 Linux cluster. Did some hand testing and things
seem to work fine.

3. I tried to run smoketest on the cluster, but I had some issues with the
test. I will be trying to run this test again soon.

4. I tried systest and generateLoad test. systest passed but generateLoad
test started spewing a lot of connection/session closed exceptions.

I hope to run systest, generateloadtest, smoktest and latencytest. If we
decide to go with the ZK on windows, then we will also write our own tests
(and do more rigorous QA). I will be happy to add these to the ZK test suite
as well.

I believe at the end of this exercise we will have fair amount of confidence
in ZK on windows. I will keep you posted.

Thanks a lot for your help.

Regards,
-Vishal

Re: QA effort to support windows as a production platform

Posted by Patrick Hunt <ph...@apache.org>.
Vishal, in general how are things going with your windows evaluation? 
Can you give a short review of what you've tested, what's working and 
what you still would like to look at? You are testing under windows 
directly, correct? (not cygwin I mean). Any chance you will be able to 
test the c, python and/or perl bindings? (although this would mean 
porting to windows compiler if i understand correctly).

We should consider updating the documentation to include detail about 
windows support if you feel comfortable. Enter a JIRA for this if you 
agree. Perhaps a wiki page detailing status and any issues running on 
that platform might also be useful? It would be great to offer (with 
confidence) ZK to users of the windows platform.

Thanks for taking on this effort, regards,

Patrick

Re: QA effort to support windows as a production platform

Posted by Patrick Hunt <ph...@apache.org>.
I can't tell for certain. Looking a bit closer the code that starts the 
server for the c tests does reference the clover jar, so my guess would 
be that it does, but the messages from clover and the build, etc.. don't 
shed any light. I didn't setup the zk clover stuff for hudson, cc'ing 
Giri who might have insight.

Re: QA effort to support windows as a production platform

Posted by Vishal K <vi...@gmail.com>.
Hi Patrick,

We are not using C clients so we are not worried about porting them to
Windows. Just out of curiosity, is there any way to confirm if the code
coverage results are a result of test-core-java. If not, I will run the
coverage tools locally.

I had tried the smoketests earlier, but I ran into some issues there. I
forgot to note down the problem. I will revisit and upload the results.
Thanks for your help.

Right, afaik that's test-core-java.

I think if you plan to run in production under windows you would want to 
run in win, not cygwin. If that's the case you'd have to port the c 
client and c client tests to some windows specific compiler.

Well the best thing would be to run one's own tests for their specific 
use cases. Short of that you've done the core set of tests that we have 
available to us. You might try the smoke/latency tests:
http://github.com/phunt/zk-smoketest
in particular you can run the latency tests from a number of clients in 
parallel and see the results.

Re: QA effort to support windows as a production platform

Posted by Vishal K <vi...@gmail.com>.
Hi Mahadev,

Thanks for your response. Currently I am running ZK without cygwin on
windows. I will give it a try on cygwin. I am not quite familiar with
cppunit. Why will cppinit give me more confidence in native windows
libraries?

I have few more questions relevant to testing:
1. How much code coverage do we get with "test-core-java"? I see 68.8%
coverage on hudson
http://hudson.zones.apache.org/hudson/job/ZooKeeper-trunk/clover/.  Does
this measure the coverage from junit tests run from "test-core-java"?

2. What would be a good and reliable set of tests that will help me verify
that the cluster holding up fine on windows. I tried to run systest and
generateload. But I am having issues with the tests (and also understanding
the output of the tests since I am not familiar with the source). The
systest did exit with output something ilke Test OK (1). I presume this is a
good sign :-) generateLoad crashed and I will look into it later. Please let
me know if you have any suggestions. Last few lines are shown below:

Re: QA effort to support windows as a production platform

Posted by Mahadev Konar <ma...@yahoo-inc.com>.
HI Vishal,
  I would be a good think to actually get cppunit working on windows (rather
than dropping it) since it would make you more confident on being able to
use the native libraries for windows.

Though there is already an open jira to try and compile librarires without
CPPIUNIT being installed on the machines.

http://issues.apache.org/jira/browse/ZOOKEEPER-316


Would you want to try and take a shot at fixing the cppunit tests?

Would be great to have cppunit tests working on cygwin!


Thanks
mahadev

Re: QA effort to support windows as a production platform

Posted by Vishal K <vi...@gmail.com>.
Hi,

I had few minor problems (
https://issues.apache.org/jira/browse/ZOOKEEPER-734) after which all junits
passed (I ran ant test-java-core).

But the build failed later in create-cppunit-configure:

-------------
test-core-java:
call-test-cppunit:
init:
check-cppunit-makefile:
create-cppunit-makefile:
init:
check-cppunit-configure:
create-cppunit-configure:
    [mkdir] Created dir:
C:\zookeeper\zookeeper-3.3.0\build\test\test-cppunit
BUILD FAILED
C:\zookeeper\zookeeper-3.3.0\build.xml:907: The following error occurred
while executing this line:
C:\zookeeper\zookeeper-3.3.0\build.xml:865: The following error occurred
while executing this line:
C:\zookeeper\zookeeper-3.3.0\build.xml:857: Execute failed:
java.io.IOException: Cannot run program
"C:\zookeeper\zookeeper-3.3.0\src\c\configure" (in directory
"C:\zookeeper\zookeeper-3.3.0\build\test\test-cppunit"): CreateProcess
error=193, %1 is not a valid Win32 application
 at java.lang.ProcessBuilder.start(ProcessBuilder.java:459)
 at java.lang.Runtime.exec(Runtime.java:593
-----------
cppunit tests should be probably dropped for windows.

Also, one point to note the dataDir in zoo.cfg should have UNIX path (or
double backslash instead of single backslash). I suppose all Java developers
might be already aware of that.

Regards,
-Vishal

Pretty seamless, just do a rolling upgrade (see the faq) of the servers. 
Then upgrade your clients. Code APIs on the client are all b/w compat.

Hi Patrick,

We have not upgraded to 3.3.0 yet. We are using 3.2.2. I did notice the
windows specific batch files in 3.3.0. How seemless is upgrade from 3.2.2 -
> 3.3.0?

I will let you know if I run into any windows related problems. Thanks.

Re: QA effort to support windows as a production platform

Posted by Patrick Hunt <ph...@apache.org>.
Are you using 3.3.0? 3.3.0 included a number of fixes for cygwin and 
includes windows specific batch files. If you are planning to deploy to 
production on windows I'd encourage you to develop under windows 
directly as well.

If you find issues, bugs, etc... be sure to enter JIRAs. Don't worry, 
you won't hurt our feelings, on the contrary we'll be happy if you 
find/fix issues on windows and make things better for everyone. (just 
make sure you are using the latest release).

Regards,

Patrick

Re: QA effort to support windows as a production platform

Posted by Vishal K <vi...@gmail.com>.
Hi,

I was able to start zookeeper on windows using cygwin. I had to do minor
changes to the shell scripts to use cygpath wherever needed.
I will run a few tests and post the progress. I greped through the zookeeper
sources just to check if ZK is using any native code.
I didn't find any, but just to confirm - is ZK using native code.

I have talked to a few guys around and they said it is fair to assume that
the programs are portable (to Windows) if they don't have native code. Just
wanted to check. Thanks.

Hi Patrick,

Thanks for your response. I start running ZK on windows and let you know if
I run into issues.

My use of ZK is exclusively 32/64bit linux, however I can tell you that 
given that the client/server are implemented in java it should work. 
Problems you might encounter would be things like NIO issues with the 
JVM implementation on windows.

Testing on windows? Pretty much 0 afaik. We do support development on 
cygwin, so provides some basic exercising of the codepaths with the 
windows jvm, however it's not likely production level qa.

This question (zk on win) has come up once or twice before, I haven't 
seen any followup from the users who asked about it previously though.

3.3.0 has batch files for running the server in windows, give those a 
try. Probably what you'd want to do is run "ant test-core-java" or 
similar in the top of the ZK release directory. This will run all the 
java tests and give you some insight into status. I'd be happy to work 
with you to land patches that address issues with ZK on windows. 
Depending on the interest level and support from win users we could 
support win as a dev/prod platform at some point in the future - having 
ongoing support for this would be important though (people interested in 
testing/fixing under win I mean). Try exercising under windows and 
create some JIRAs based on what you find.

Patrick
