Subject [jira] [Commented] (YARN-231) Add persistent store implementation for RMStateStore
Date Fri, 21 Dec 2012 21:41:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13538442#comment-13538442

Bikas Saha commented on YARN-231:
---------------------------------

{noformat}
Code	Warning
IS	Inconsistent synchronization of org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore.zkClient;
locked 81% of time
IS	Inconsistent synchronization of org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore.zkSessionTimeout;
locked 50% of time
{noformat}
These are the warnings. I looked at the code and I dont see a synchronization issue. Maybe
a different pair of eyes might spot something. If its clean I will disable the warning for
that part of the code.
