Subject [jira] [Commented] (YARN-5825) ProportionalPreemptionalPolicy could use readLock over LeafQueue instead of synchronized block
Date Thu, 12 Jan 2017 00:43:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-5825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15819695#comment-15819695

Andrew Wang commented on YARN-5825:
-----------------------------------

Doing a release notes sweep for 3.0.0-alpha2, noticed this JIRA. If it's incompatible, should
it have been committed to branch-2?

Also, if this is incompatible, could someone also add a release note detailing the exposure?
Thanks!

> Currently in PCPP, {{synchronized (curQueue)}} is used in various places. Such instances
could be replaced with a read lock. Thank you [~jianhe] for pointing out the same as comment
