Subject [jira] [Commented] (HDFS-4200) Reduce the size of synchronized sections in PacketResponder
Date Fri, 16 Nov 2012 21:59:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13499178#comment-13499178
] 

Eli Collins commented on HDFS-4200:
-----------------------------------

This is great Suresh. The following hbase test (run from hbase trunk) is a good stress test
of the synchronization in this code. If you want to run it with your change you need to publish
your change to a local mvn repo (using the same hadoop version in the hbase pom).

{code}
mvn test -Dtest=TestMiniClusterLoadSequential -P localTests -DredirectTestOutputToFile=true
-Dhadoop.profile=2.0
{code}

> The size of synchronized sections can be reduced in PacketResponder. Also the methods
in the PacketResponder are long and need refactoring.
