Subject [jira] Commented: (HDFS-1398) HDFS federation: Upgrade and rolling back of Federation
Date Tue, 14 Sep 2010 01:12:32 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12909079#action_12909079
] 

Tanping Wang commented on HDFS-1398:
------------------------------------

As a continuous effort of HDFS-1365,  HDFS-1394 and HDF-S1397, we are 
-- introducing VERSION (ID) files into HDFS
-- modifying the namenode -format 
-- storing the VERSION (ID) files into different storage directories in Federation release

This effects the upgrade and rolling back process of HDFS.
