[jira] [Created] (HBASE-17282) Reduce the redundant requests to meta table

Duo Zhang created HBASE-17282:
---------------------------------

             Summary: Reduce the redundant requests to meta table
                 Key: HBASE-17282
                 URL: https://issues.apache.org/jira/browse/HBASE-17282
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang


This usually happens at startup when the meta cache is empty. There will be a lot of locating requests, but most of will have same results. Things become worse if we do batch operations with AsyncTable as we will send a locating request for each operation concurrently.

We need to reduce the redundant requests to meta table.
