Subject [jira] [Commented] (HDFS-2452) OutOfMemoryError in DataXceiverServer takes down the DataNode
Date Wed, 26 Oct 2011 05:01:33 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13135712#comment-13135712
] 

Konstantin Shvachko commented on HDFS-2452:
-------------------------------------------

As Jakob noted to me the patch that went into trunk still has the 30 sec sleep in the test,
while in the patch for 0.22 branch it was eliminated. Uma, do you know what happened there?
