Subject [jira] [Commented] (HDFS-4179) BackupNode: allow reads, fix checkpointing, safeMode
Date Fri, 16 Nov 2012 19:12:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13499024#comment-13499024
] 

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

As you know, the policy for trunk is review-then-commit. Unless there is someone willing to
+1, I don't think you can commit it without an exception to the policy. If you think an exception
is warranted, we should discuss it on the mailing list first in order to set out some guidelines
for when you don't need RTC on trunk.
