Subject [jira] [Commented] (HIVE-11527) bypass HiveServer2 thrift interface for query results
Date Mon, 29 Feb 2016 12:01:18 GMT


Takanobu Asanuma commented on HIVE-11527:

Hi [~sershe], [~jingzhao]

Sorry for my late action.

As I said in the last comment, since jdbc clients may not be able to resolve the HA namespace,
HiveServer2 should resolve it with WebHdfsFileSystem and return the final FQDN to jdbc clients.
But currently, WebHdfsFileSystem does not have the API like that. So I want to implement the
public API in WebHdfsFileSystem. What do you think about that?

> 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
