Help with HBaseTestingUtility / MiniDFSCluster

Hi all,

I am having an issue starting the a mini cluster for the HBaseTestingUtility.  In short I can on Mac OSX, but cannot on Linux.   But the error is cryptic and I don't know what to do next.

I submitted a ticket with full details on StackOverflow, 

http://stackoverflow.com/questions/17625938/hbase-minidfscluster-java-fails-in-certain-environments

But when I call .startMiniCluster  on an instance of HBaseTestingUtility , on Linux (CentOS x86_64), I receive this error:



ERROR in (create-table) (MiniDFSCluster.java:426)
Uncaught exception, not in assertion.
expected: nil
  actual: java.lang.NullPointerException: null
 at org.apache.hadoop.hdfs.MiniDFSCluster.startDataNodes (MiniDFSCluster.java:426)
    org.apache.hadoop.hdfs.MiniDFSCluster.<init> (MiniDFSCluster.java:284)
    org.apache.hadoop.hbase.HBaseTestingUtility.startMiniDFSCluster (HBaseTestingUtility.java:444)
    org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster (HBaseTestingUtility.java:612)
    org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster (HBaseTestingUtility.java:568)
    org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster (HBaseTestingUtility.java:555)

I would appreciate help in finding out whats going on and how to set up my ENV to use the HBaseTestingUtility.

Thanks
David

Hi David,

I filled in an answer on SO.  Hopefully that provides some context on the
underlying problem.

Quick Google "MiniHBaseCluster master not initialized" gives this link:
http://girlincomputerscience.blogspot.com/2012_12_01_archive.html

with the same advice: umask 022

Unfortunately, it did not help in my case (Mac OSX).

Hi Andrew,

Yes that solves it.  Care to answer the SO question with some details about why?  I put a 100pt bounty.

What HBase version are you using for your Closure test ?

Re: HBaseTestingUtility Failing

Posted by Gary Helmling <gh...@gmail.com>.
Hi David,

I can't say for certain given the test output (would need to see the logs
generated by the datanodes), but there is a common issue running mini
cluster unit tests if the environment's umask is not set to 022.  This is
due to https://issues.apache.org/jira/browse/HDFS-2556 where the mini
cluster DNs fail fast if the dfs.data.dir permissions do not match what is
expected.

We ran into this issue setting up builds or our hRaven project (which uses
HBaseTestingUtility) with Travis CI.  Modifying our .travis.yml file by
adding the following line fixed the problem:

script: umask 0022 && mvn test


This should override the umask for the test process for your project.

Re: HBaseTestingUtility Failing

Posted by David Williams <mo...@gmail.com>.
I doubt this has anything todo specifically with CentOS etc.  I am not privy to your setup up but the steps to reproduce are easy.

1.  Get a linux distro such as CentOS.   Put it say, in a VM such as Vmware Fusion on Mac.
2.  Install Java
3.  Try to start a mini cluster (will fail)

The bottom line is there is an uncaught null pointer exception in the Testing Utility.  Is this considered to be of little priority?

Ted, what linux distribution is that?

It's pretty much a prerequisite for me to be able to introduce HBase into production.  We have a strict continuous integration process and I need to be able to build software for use with our Hbase cluster in our CI environment including running all tests.  Our CI environment does not have its own test cluster and the chances of that becoming the case are slim.  Besides the relative convenience of the testing utility is great.

Re: HBaseTestingUtility Failing

I would be busy today so expect delay in future response.

bq. Recall that this is not an issue on Mac OSX for some odd reason

I didn't reproduce the issue you mentioned on either OSX or Linux.

Maybe people who use CentOS for ci can comment on this matter.

Cheers

HBaseTestingUtility Failing

Posted by David Williams <mo...@gmail.com>.
Hi Ted,

So, what would you recommend in terms of getting a working HbaseTestingUtility or just unit testing in general?   It's pretty much a prerequisite for me to be able to introduce HBase into production.  We have a strict continuous integration process and I need to be able to build software for use with our Hbase cluster in our CI environment including running all tests.  Our CI environment does not have its own test cluster and the chances of that becoming the case are slim.  Besides the relative convenience of the testing utility is great.  

> check out http://svn.apache.org/repos/asf/hadoop/common/branches/branch-1

I don't know anything about the hadoop source, this branch, or what is needed to run their JUnit tests.  This is pretty much a non starter for me.

Recall that this is not an issue on Mac OSX for some odd reason, only on CentOS and Linux VM's such as in use by travis-ci.  You can see the failed build output here:

https://travis-ci.org/mobiusinversion/hbase

Recall also that I opened a travis-ci ticket and the travis support was able to reproduce success on Mac OSX and failure on Linux.

https://github.com/travis-ci/travis-ci/issues/1240

I started a bounty on SO:

http://stackoverflow.com/questions/17625938/hbase-minidfscluster-java-fails-in-certain-environments


St.Ack - what do you think the relative priority of this issue might be?

Re: Help with HBaseTestingUtility / MiniDFSCluster

Posted by Ted Yu <yu...@gmail.com>.
Here is one way of figuring out whether hdfs experiences the same issue is
the following:

check out http://svn.apache.org/repos/asf/hadoop/common/branches/branch-1
use the command to find out which tests create MiniDFSCluster: find . -name
'*.java' -exec grep 'new MiniDFSCluster(' {} \; -print
run one of the tests: ant test-core -Dtestcase=TestCopyCommitter

See if there is similar exception.

On my Mac, I got:

    [junit] Running org.apache.hadoop.tools.distcp2.mapred.TestCopyCommitter
    [junit] Tests run: 6, Failures: 0, Errors: 0, Time elapsed: 12.283 sec

Re: Help with HBaseTestingUtility / MiniDFSCluster

Posted by David Williams <mo...@gmail.com>.
Hi Ted,

I'd be interested to know more about an hdfs issue.  I was go to look further into the line of reasoning you mentioned about the call to getAddress. 

MiniDFSCluster.java, line 426:
String ipAddr = dn.getSelfAddr().getAddress().getHostAddress();

So that one of getSelfAddr or getAddress returned NULL.   Is there something new about hdfs or are the two related?

Most likely this is an hdfs issue.

Do you mind trying the following change to see if the problem persists for
latest 0.94 release ?

Thanks

Re: Help with HBaseTestingUtility / MiniDFSCluster

Hi Ted,

In terms of versions, here are the jars I'm using, which come from Maven Central.

org.apache.hadoop/hadoop-core "1.2.0"
org.apache.hbase/hbase "0.94.6.1"
org.apache.hadoop/hadoop-test "1.2.0"
org.apache.hbase/hbase "0.94.6.1" :classifier "tests"

The flag ':classifier "tests"' above is a specific instruction to to the Leiningen 2.0 to use the pomegranate library to handle Sonatype Aether and dynamic runtime modification of the classpath, which in this case is needed to import org.apache.hadoop.hbase HBaseTestingUtility.

https://github.com/cemerick/pomegranate


I just checked on address resolution, on my Mac OSX where the TestingUtility passes:

user=> (import 'java.net.InetSocketAddress)
java.net.InetSocketAddress
user=> (def x (InetSocketAddress. 8000))
#'user/x
user=> (.getAddress x)
#<Inet4Address 0.0.0.0/0.0.0.0>
user=>

Then I check on a CentOS vm, the unit tests still fail but the address resolution also worked in the repl and produced the same output as above.

Re: Help with HBaseTestingUtility / MiniDFSCluster

Posted by Ted Yu <yu...@gmail.com>.
I installed lein on Mac and Linux.

I tried 'lein test' on both platforms and the test passed on both:

lein test hbase.table-test
Starting DataNode 0 with dfs.data.dir:
/homes/hortonzy/mobius/target/test-data/246828b9-1be9-4949-9bbc-b215b378fb67/dfscluster_9ed0bd88-d309-4fed-9823-3bbf86973ae4/dfs/data/data1,/homes/hortonzy/mobius/target/test-data/246828b9-1be9-4949-9bbc-b215b378fb67/dfscluster_9ed0bd88-d309-4fed-9823-3bbf86973ae4/dfs/data/data2
Cluster is active

Ran 11 tests containing 14 assertions.
0 failures, 0 errors.

Here is Linux OS:

Linux a.net 2.6.32-220.23.1.el6.YAHOO.20120713.x86_64 #1 SMP Fri Jul 13
11:40:51 CDT 2012 x86_64 x86_64 x86_64 GNU/Linux

Looking at MiniDFSCluster.java, line 426:

      String ipAddr = dn.getSelfAddr().getAddress().getHostAddress();

It seems dn.getSelfAddr().getAddress() returned null.

According to:
http://docs.oracle.com/javase/7/docs/api/java/net/InetSocketAddress.html#getAddress()

This would mean address resolution problem.

Can you check ?

Cheers
