Subject [jira] [Updated] (YARN-1378) Implement a RMStateStore cleaner for deleting application/attempt info
Date Wed, 04 Dec 2013 05:16:35 GMT

     [ https://issues.apache.org/jira/browse/YARN-1378?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jian He updated YARN-1378:

    Attachment: YARN-1378.4.patch

- Add a new configuration for controlling the number of completed apps kept in state store,
by default, it equals to max_completed_apps in RM memory
- Fix some redundant loggings when loading RM state.
- Fixed a bug in RMAppImpl.RMAppRecoveredTransition that as long as the final state of the
app is available, return the final state of the app.
- changed zk delete ops to use version -1 to match all versions
- remove RMAppRemovedEvent and associated stuff

> Now that we are storing the final state of application/attempt instead of removing application/attempt
info on application/attempt completion(YARN-891), we need a separate RMStateStore cleaner
for cleaning the application/attempt state.
