Subject [jira] [Commented] (HDFS-2452) OutOfMemoryError in DataXceiverServer takes down the DataNode
Date Thu, 20 Oct 2011 21:27:10 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13132059#comment-13132059
] 

Uma Maheswara Rao G commented on HDFS-2452:
-------------------------------------------

I think test wont work as expected because, throwing exception from run will not get propagated
to parent thread. Silently child threads will die.
I am not sure,we can throw the exception before actually spawning the thread.

I feel simple, the option would be from DataXceiver Constructor.


Thanks
Uma
