-------------------------------------------
cxzl25 opened a new pull request, #5686:
URL: https://github.com/apache/hadoop/pull/5686
### Description of PR
Now the job history server provides RPC services. If the Client passes the
CallerContext, the RPC will create a MoveIntermediateToDone thread. The
CallerContext supports parent-child thread variable inheritance, so the
MoveIntermediateToDone thread may always be the CallerContext.
