Subject [jira] [Updated] (YARN-7663) RMAppImpl:Invalid event: START at KILLED
Date Sat, 06 Jan 2018 06:14:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7663?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

lujie updated YARN-7663:
    Attachment: YARN-7663_5.patch


Rather than calling createNewTestApp then throwing away the results, it would be cleaner to
extend createNewTestApp to take a boolean parameter specifying whether to create an app with
invalid state transition detection or without. Alternatively you could factor out the rmContext,
scheduler, and conf setup from createNewTestApp so the test can leverage it without needing
to do all the other, unrelated stuff in createNewTestApp.

After I implement both of the two plans, I perform the second plan because it will add less
code and more cleaner.  In the new patch , I  factor out the unrelated arguments that passed(set
them to null) to  constructed function of RMAppImpl as more as possible.
