Subject [jira] Commented: (HADOOP-4278) TestDatanodeDeath failed occasionally
Date Wed, 15 Oct 2008 01:18:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12639684#action_12639684

dhruba borthakur commented on HADOOP-4278:
------------------------------------------

If you look at the attached log to this JIRA, one can clearly see that the second datanode
is being killed by the test. Hoqeer, the killing is done by sending interrupts to the second
datanode. The PacketResponder thread of the second datanode sends back -2 to the first datanode
beucase it encounters this InterruptedException. The firstdatanode thinks that the second
datanode is good beucase it did send back a response, so the bad datanode must be the third
one in the list.
