Date Fri, 27 Feb 2015 08:54:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-2962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14339900#comment-14339900

Tsuyoshi Ozawa commented on YARN-2962:
--------------------------------------

[~varun_saxena], Yes, RMStateStore#checkVersion validates the version. I think this change
can be a major upgrade of the version.

> We ran into this issue where we were hitting the default ZK server message size configs,
primarily because the message had too many znodes even though they individually they were
all small.
