> Currently, the config keys for thread number of meta server and server operations in HMaster are same: 
> See: HMaster.java #993
> {code}
> this.service.startExecutorService(ExecutorType.MASTER_SERVER_OPERATIONS,
>       conf.getInt("hbase.master.executor.serverops.threads", 5));
>    this.service.startExecutorService(ExecutorType.MASTER_META_SERVER_OPERATIONS,
>       conf.getInt("hbase.master.executor.serverops.threads", 5));
> {code}
> In large cluster, we usually enlarge the thread number for server operation separately to make the master handle   regionserver shutdown events quickly in some extremely cases.
> So I think we need separate the thread number config for the two operations.
> Suggestions are welcomed. Thanks~
