Subject [jira] [Commented] (HIVE-11527) bypass HiveServer2 thrift interface for query results
Date Sat, 18 Jun 2016 00:26:05 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15337300#comment-15337300

Thejas M Nair commented on HIVE-11527:
--------------------------------------

Thanks for working on this [~tasanuma0829]!
I have added some comments in review board.
This would break backward compatibility with old clients (old jdbc drivers). HS2 supports
having older drivers talking to new servers. 
The bypass should be disabled if the client is using a thrift api version older than this
api version, to support this backward compatibility.

> Right now, HS2 reads query results and returns them to the caller via its thrift API.
> There should be an option for HS2 to return some pointer to results (an HDFS link?) and
for the user to read the results directly off HDFS inside the cluster, or via something like
WebHDFS outside the cluster
