Tsuyoshi OZAWA commented on YARN-1239:
--------------------------------------
[~jianhe], maybe RMStateVersionIncompatibleException file seems to be missing
in your latest patch.
One trivial point:
{code}
- optional int64 start_time = 2;
- optional ApplicationSubmissionContextProto application_submission_context =
3;
- optional string user = 4;
+ optional ApplicationSubmissionContextProto application_submission_context =
2;
+ optional string user = 3;
+ optional int64 start_time = 4;
{code}
I think we should not swap these fields unless we think it's reasonable.
