Subject [jira] [Commented] (YARN-4807) MockAM#waitForState sleep duration is too long
Date Thu, 31 Mar 2016 05:32:25 GMT

    [ https://issues.apache.org/jira/browse/YARN-4807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15219380#comment-15219380

Yufei Gu commented on YARN-4807:

Thanks [~kasha@cloudera.com] for review and very nice suggestions. 

Besides return type, there are even more inconsistencies among these {{waitForState}}, some
ones have a minimum waiting time(1000ms), some one don't. I appreciate if someone can explain
why we need a minimum waiting time. Another inconsistency is some wait function don't have
a timeout, they can wait for ever. And there are more, e.g. some functions use {{LOG.info}}
and others use {{System.out.println}} to print messages. 

It's better to discuss and make a decision to solve these inconsistencies. Or put them in
a follow up JIRA.
