Subject [jira] [Commented] (YARN-3142) Improve locks in AppSchedulingInfo
Date Thu, 05 Feb 2015 10:13:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-3142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14306949#comment-14306949
] 

Varun Saxena commented on YARN-3142:
------------------------------------

As per previous discussion, it is primarily about having a read/write lock instead of a synchronized
method.
We can use thread safe data structures as well, wherever possible and keep only critical sections
inside a lock.
Fine grained locking however, whether it can be handled as part of this JIRA, is open to discussion.
Thanks for your interest but I would like to work on this. I already had a cursory glance
at all the classes initially mentioned in the parent JIRA when that was raised.
