Subject [jira] [Created] (YARN-6967) Limit application attempt's diagnostic message size thoroughly
Date Tue, 08 Aug 2017 12:02:00 GMT
Chengbing Liu created YARN-6967:
-----------------------------------

             Summary: Limit application attempt's diagnostic message size thoroughly
                 Key: YARN-6967
                 URL: https://issues.apache.org/jira/browse/YARN-6967
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.8.1
            Reporter: Chengbing Liu
            Assignee: Chengbing Liu


YARN-6125 implemented {{BoundedAppender}} and applied to the field {{diagnostics}} to limit
the diagnostic message's size.

However, some code bypasses this limit. In {{RMAppAttemptImpl.rememberTargetTransitionsAndStoreState(...)}},
a local variable {{diags}} will finally be written into ZooKeeper if ZKRMStateStore is used.

A simple fix is to also use {{BoundedAppender}} for the local variable.
