Subject [jira] [Commented] (YARN-353) Add Zookeeper-based store implementation for RMStateStore
Date Fri, 05 Jul 2013 00:15:48 GMT

    [ https://issues.apache.org/jira/browse/YARN-353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13700395#comment-13700395

Jian He commented on YARN-353:
------------------------------

bq. I dont think it makes sense to have default value for this. ZK location is not something
we control and we cannot assume it to be running on some default location.
Yes, we can not assume which location ZK is ruining on, but I think the result would be the
same if we provide a default or leave it empty, botch cases should raise connect exception
or something, which leads the user to config the true address. One bonus doing such might
make user easier in test mode where ZK is running on its defaults, your opinion?
