Subject [jira] [Created] (HIVE-16055) HiveServer2: Prefetch a batch from the result file so that the RPC fetch request has results available in memory

---------------------------------------

             Summary: HiveServer2: Prefetch a batch from the result file so that the RPC fetch
request has results available in memory
                 Key: HIVE-16055
                 URL: https://issues.apache.org/jira/browse/HIVE-16055
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2
    Affects Versions: 2.2.0
            Reporter: Vaibhav Gumashta


Currently:
Client Fetch -> RPC -> Server -> File Read (via FetchTask#fetch).

If the Fetch RPC can have the next batch of results available to it in memory, we can return
the batch faster to the client.
