Subject [jira] Commented: (HDFS-1632) HDFS Federation: data node storage structure changes and introduce block pool storage for Federation.
Date Thu, 24 Feb 2011 00:03:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12998624#comment-12998624
] 

Suresh Srinivas commented on HDFS-1632:
---------------------------------------

As I posted in another jira, this commit is to a feature branch and not trunk. As was posted
earlier by Owen in the  mailing list, instead of posting a jumbo patch, we are creating smaller
jiras, describing the change and posting smaller patches.

Please comment on these jiras, irrespective of whether it is committed or not. If you do not
do it now, there is an opportunity to comment again, when federation branch gets merged to
the trunk.

All comments will be considered and new jiras will be created to address the required changes.
