Subject [jira] [Commented] (HDFS-4376) Intermittent timeout of TestBalancerWithNodeGroup
Date Fri, 11 Oct 2013 20:06:44 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13793001#comment-13793001

Tsz Wo (Nicholas), SZE commented on HDFS-4376:

Hi Junping, thanks for working hard on this.

Source.chooseNextBlockToMove() also changes scheduledSize.  I think we should change scheduledSize
to private so that we could enforce synchronization inside BalancerDatanode.

> HDFS-4261 fixed several issues with the balancer and balancer tests, and reduced the
frequency with which TestBalancerWithNodeGroup times out. Despite this, occasional timeouts
still occur in this test. This JIRA is to track and fix this problem.
