Subject [jira] [Commented] (YARN-353) Add Zookeeper-based store implementation for RMStateStore
Date Tue, 09 Jul 2013 19:11:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13703665#comment-13703665
] 

Karthik Kambatla commented on YARN-353:
---------------------------------------

Few comments/nits before we get this in:
# Add test to check the disconnect and reconnect logic, essentially the switch-cases in processWatchEvent
# YarnConfiguration: how about creating a common prefix for all of zk-state-store related
parameters?
# Make the ZKRMStateStore#NUM_RETRIES configurable with default set to 3.
# ZKRMStateStore#getNewZooKeeper need not be synchronized
# Might be cleaner to move zkDoWithRetries to ZkAction
# Just thinking out loud: would it make sense to move the *WithRetries methods to ZkAction
itself, and may be rename it if required. All of the methods seem like util methods and moving
them out might make it more readable
