Subject [jira] Commented: (HDFS-592) Allow client to get a new generation stamp from NameNode
Date Wed, 16 Sep 2009 14:28:57 GMT

    [ https://issues.apache.org/jira/browse/HDFS-592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756048#action_12756048

Konstantin Boudnik commented on HDFS-592:
-----------------------------------------

bq. Kan, thanks for catching this. ClientName should never be null in the real system. But
anyway the new patch checks the null case and adds a new unit test for this.
There's always a probability for the worst
