Subject [jira] [Commented] (HDFS-4261) TestBalancerWithNodeGroup times out
Date Thu, 06 Dec 2012 01:24:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13511011#comment-13511011
] 

Tsz Wo (Nicholas), SZE commented on HDFS-4261:
----------------------------------------------

+1 patch looks good.

Balancer is a shell command so that it uses System.out/err directly.  It also has a LOG so
that the log level can be changed.  We may want to carefully think about when to use System.out/err
and when to use LOG for each message.  Let's don't change the messages here.  We may change
them in another JIRA if it is desirable.

BTW, the test case is excellent!

> When I manually ran TestBalancerWithNodeGroup, it always timed out in my machine.  Looking
at the Jerkins report [build #3573|https://builds.apache.org/job/PreCommit-HDFS-Build/3573//testReport/org.apache.hadoop.hdfs.server.balancer/],
TestBalancerWithNodeGroup somehow was skipped so that the problem was not detected.
