    Description

      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.
