Subject [jira] [Commented] (HDFS-4179) BackupNode: allow reads, fix checkpointing, safeMode
Date Sat, 17 Nov 2012 08:01:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13499370#comment-13499370
] 

Todd Lipcon commented on HDFS-4179:
-----------------------------------

OK, to be clear: I'm not interested in reviewing it, because I don't see what the BN offers
aside from other already-existing approaches. So, I can't personally devote time to it.

And I don't think "no one wants to review this" is valid reason to commit without a review.

> BackupNode should be allowed to accept read command. Needs some adjustments in checkpointing
and with safe mode.
