Subject [jira] [Commented] (YARN-2962) ZKRMStateStore: Limit the number of znodes under a znode
Date Wed, 14 Jan 2015 15:55:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14277106#comment-14277106
] 

Karthik Kambatla commented on YARN-2962:
----------------------------------------

The proposed approach sounds reasonable. How about adding a config that controls the number
of digits (decimal places) to get at 2:2 or 1:3 split.

> 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.
