Subject [jira] [Updated] (HDFS-4200) Reduce the size of synchronized sections in PacketResponder
Date Wed, 26 Feb 2014 23:45:21 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Wang updated HDFS-4200:

    Attachment: hdfs-4200-branch-2.patch

I was testing out a backport of the rolling upgrades branch to branch-2, and ran into conflicts
because this JIRA isn't in branch-2.

Attached patch backports it. After applying it, the trunk and branch-2 versions are exactly
the same.

in the PacketResponder are long and need refactoring.
