ruanhui created HBASE-27355:
-------------------------------

             Summary: Separate meta read requests from master and client 
                 Key: HBASE-27355
                 URL: https://issues.apache.org/jira/browse/HBASE-27355
             Project: HBase
          Issue Type: Improvement
          Components: IPC/RPC
    Affects Versions: 3.0.0-alpha-3
            Reporter: ruanhui
            Assignee: ruanhui
             Fix For: 3.0.0-alpha-4


If we have a large number of store files in a single region or the response from hdfs is slow, the region transition can be slow, the client may put a lot of pressure on the meta server when retrying. This may block the master system read requests. Maybe we can set a special priority for the master request to isolate read requests from master and client.
