Help on running JUnit test cases on Hadoop-Common-trunk

[Elizabeth Thomas <em...@gmail.com>]

Folks,

I am getting started on the
http://wiki.apache.org/hadoop/HowToContribute section
of Hadoop.

I attempted to run all the unit test cases on a fresh checked-out code from
the hadoop common trunk
(http://svn.apache.org/repos/asf/hadoop/common/trunk: revision -
1513368). But I am seem to be getting the following
failures/errors.

===================================================================
Results :

Failed tests:
testGracefulFailoverFailBecomingActive(org.apache.hadoop.ha.TestZKFailoverController):
Did not fail to graceful failover when target failed to become active!

testGracefulFailoverFailBecomingStandby(org.apache.hadoop.ha.TestZKFailoverController):
expected:<1> but was:<0>

testGracefulFailoverFailBecomingStandbyAndFailFence(org.apache.hadoop.ha.TestZKFailoverController):
Failover should have failed when old node wont fence
  testCachingRelaysResolveQueries(org.apache.hadoop.net.TestStaticMapping):
Expected two entries in the map Mapping: cached switch mapping relaying to
static mapping with single switch = false(..)

testCachingCachesNegativeEntries(org.apache.hadoop.net.TestStaticMapping):
Expected two entries in the map Mapping: cached switch mapping relaying to
static mapping with single switch = false(..)
  testResolve(org.apache.hadoop.net.TestTableMapping): expected:</[rack1]>
but was:</[default-rack]>
  testTableCaching(org.apache.hadoop.net.TestTableMapping):
expected:</[rack1]> but was:</[default-rack]>
  testClearingCachedMappings(org.apache.hadoop.net.TestTableMapping):
expected:</[rack1]> but was:</[default-rack]>
  testNormalizeHostName(org.apache.hadoop.net.TestNetUtils):
expected:<[67.215.65.145]> but was:<[UnknownHost123]>

Tests in error:
  testGracefulFailover(org.apache.hadoop.ha.TestZKFailoverController): test
timed out after 25000 milliseconds
  testChgrp(org.apache.hadoop.fs.TestFsShellReturnCode): test timed out
after 30000 milliseconds

Tests run: 2096, Failures: 9, Errors: 2, Skipped: 71
===================================================================

Is there a pre-requisite for running these JUnit test cases? or any service
to be up and running on my Ubuntu machine?

As given in the contribute section, I would like to get the unit cases to
run successfully before I start compiling my patch changes.

Could anybody help here?

Thanks in advance,
Elizabeth

Elizabeth,

 Welcome to Apache Hadoop!

 This seems like we either have broken or flaky tests (TestZKFailoverController). 

 Looks like you are already engaged on HADOOP-9745. If you are feeling adventurous, we'd love to get your help in fixing them too.

thanks,
Arun
