Subject [jira] [Commented] (YARN-5123) SQL based RM state store
Date Mon, 23 May 2016 09:20:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-5123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15296141#comment-15296141

Bala Nathan commented on YARN-5123:
-----------------------------------

Just have a few questions:

1) Can you describe the issues you faced with using ZK state store pls? 
2) I'm assuming the SQLStateStore can be based off mysql too? Is there a particular reason
for using postgresql ?

> In our setup,  zookeeper based RM state store didn't work. We ended up implementing our
own SQL based state store. Here is a patch, if anybody else wants to use it.
