Date Fri, 22 Nov 2013 02:12:36 GMT
Omkar Vinit Joshi created YARN-1436:
---------------------------------------

             Summary: ZKRMStateStore should have separate configuration for retry period.
                 Key: YARN-1436
                 URL: https://issues.apache.org/jira/browse/YARN-1436
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Omkar Vinit Joshi
            Assignee: Jian He


Problem :- Today we have zkSessionTimeout period which is getting used for zookeeper session
timeout and for ZKRMStateStore based retry policy. 

Proposed suggestion :- Ideally we should have different configuration knobs for this. 
Ideal values for 
zkSessionTimeout should be :- number of zookeeper instances participating in quorum * per
zookeeper session timeout. see
{code}
org.apache.zookeeper.ClientCnxn.ClientCnxn()..
connectTimeout = sessionTimeout / hostProvider.size();
{code}
retry policy... (may be retry time period or count)
