Subject [jira] Commented: (HDFS-1540) Make Datanode handle errors to namenode.register call more elegantly
Date Tue, 28 Dec 2010 01:29:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975401#action_12975401
] 

Konstantin Shvachko commented on HDFS-1540:
-------------------------------------------

Same here. Looks like you remove the timeout exception, which we still need to track. Besides,
when DN receives the timeout exception it doesn't die, but retries. Which version is it targeted
for?

> When a datanode receives a "Connection reset by peer" from the namenode.register(), it
exits. This causes many datanodes to die.
