[jira] [Commented] (HBASE-21890) Use execute instead of submit to submit a task in RemoteProcedureDispatcher

    [ https://issues.apache.org/jira/browse/HBASE-21890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16767089#comment-16767089 ] 

Duo Zhang commented on HBASE-21890:
-----------------------------------

Ok we have delay task... So we have to eat the returned Future. Let me change to use ListenableFuture...

> 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.
