Subject [jira] [Commented] (HDFS-4261) TestBalancerWithNodeGroup times out
Date Wed, 12 Dec 2012 04:03:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13529610#comment-13529610
] 

Junping Du commented on HDFS-4261:
----------------------------------

Yes. For each iteration, a new Balancer object is created but the parameter p is the old one
and passed to constructor of balancer every time. As p contains Balancing policy which do
accumulation of nodes' capacity, it needs to be cleaned up in each iteration. So may be resetData()
is still necessary here?
Also, it seems odd that testBalancerWithRackLocality() in Jenkins ends with NO_MOVE_PROGRESS
but run perfect in my env. Shall we address here or file a separated JIRA to track this?

> 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.
