Subject [jira] [Commented] (HDFS-3126) Journal stream from the namenode to backup needs to have a timeout
Date Fri, 30 Mar 2012 01:13:26 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13241986#comment-13241986
] 

Hari Mankude commented on HDFS-3126:
------------------------------------

Attaching a patch which increases the rpc timeout to 30secs.

Without rpc timeout, journal call from active to backup blocks if backup node has an uncontrolled
shutdown. Also, journal is added with required set to true. This causes active NN to exit
when backupnode has an uncontrolled shutdown.
