Subject [jira] [Commented] (HDFS-2881) org.apache.hadoop.hdfs.TestDatanodeBlockScanner Fails Intermittently
Date Mon, 25 Jun 2012 16:57:44 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13400637#comment-13400637

Kihwal Lee commented on HDFS-2881:
----------------------------------

It failed in one of the precommit builds. It looks different this time.

https://builds.apache.org/job/PreCommit-HDFS-Build/2683//testReport/

While waiting for the two bad replicas, the blocks were fixed. So waitCorruptReplicas() only
saw < 2 in each loop. Moreover, the first corrupt block was reported by DFSClient while
this method was reading the file and got fixed (rereplicate/invalidate) before it looped,
without involving BlockScanner.
