Subject [jira] [Commented] (YARN-2921) MockRM#waitForState methods can be too slow and flaky
Date Wed, 03 Dec 2014 23:51:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233684#comment-14233684
] 

Karthik Kambatla commented on YARN-2921:
----------------------------------------

One way to handle this would be to (1) sleep for a smaller duration and (2) check for states
matching the state provided or later ones. The other option is to either notify waiters when
an app reaches a state, or capture all the states an app visits.

> MockRM#waitForState methods currently sleep for too long (2 seconds and 1 second). This
leads to slow tests and sometimes failures if the App/AppAttempt moves to another state.
