             Summary: Separate the thread number configs for meta server and server operations
                 Key: HBASE-13348
                 URL: https://issues.apache.org/jira/browse/HBASE-13348
             Project: HBase
          Issue Type: Bug
            Reporter: Liu Shaohui
            Assignee: Liu Shaohui


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~
