Subject [jira] [Commented] (YARN-2962) ZKRMStateStore: Limit the number of znodes under a znode
Date Mon, 20 Mar 2017 20:18:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-2962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15933461#comment-15933461

Daniel Templeton commented on YARN-2962:
----------------------------------------

Thanks for updating the patch, [~varun_saxena].  Looks like you addressed most of my comments.
 I took a look again at the ones you didn't address, and I'm fine with leaving them unaddressed.
 One minor quibble in the new patch: "deduct" is misspelled as "dedcut".  Otherwise, LGTM.

> 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.
