Duo Zhang updated HBASE-21890:
------------------------------
    Description: Found this when implementing HBASE-21875, the 
UncaughtExceptionHandler will not be invoked if you use submit to submit the 
task, as by design, you should use the returned Future object to get the 
result(exception).  (was: Found this when implementing HBASE-21875, the 
UncaughtExceptionHandler will not be invoked if you use submit to submit the 
task, as by design, you should use the returned Future object to get the 
result(exception).

As we do not care the return value here, let's change to use execute method.)

> Should deal with the returned Future for RemoteProcedureDispatcher.submitTask
