Subject [jira] Commented: (HDFS-1715) HDFS Federation: warning/error not generated when datanode sees inconsistent/different Cluster ID between namenodes
Date Thu, 03 Mar 2011 20:25:37 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13002187#comment-13002187
] 

Boris Shkolnik commented on HDFS-1715:
--------------------------------------

when a namenode with wrong cluster id tries to connect to a Datanode we should reject the
connection and shutdown the thread. But datanode will keep running.

Also we need to make sure that setting of cluster id is properly synchronized because it is
accessed from different threads (probably at the same time).
