Subject [jira] [Commented] (HIVE-4629) HS2 should support an API to retrieve query logs

Dong Chen commented on HIVE-4629:
---------------------------------

Hi, [~thejas], [~brocknoland], [~cwsteinbach], thanks for your precious comments. I am working
on the updated patch to address these comments, and will let you know when the updated patch
is uploaded.

bq. Earlier patch also had a method in HiveStatement to get the log. I think that will be
convenient for many users, though we need to be careful and specify that is the only non jdbc
function that is part of a public API in it. But this can also be done as follow up work in
separate jira.

[~thejas], you are right, adding a method in HiveStatement to get the log is convenient for
users. I filed a Jira HIVE-7615 and planed to add the getting log API in jdbc level there.

bq. I didn't see this in the patch. Are you referring to something in the Thrift IDL file
or something else?

[~cwsteinbach], [~brocknoland], the latest patch still does not fulfill the comments about
backward compatibility. I will update the patch soon and let you know. :)
The Thrift level interface TCLIService is OK. 
For client and service layer interface ICLIService, although it is not RPC and is not a public
API of Hive, I think making it follow the single request/response struct mode is also good.
Will make the new fetchResults method follow the single request/response struct model. Then
remove those old fetchResults methods.

> HiveServer2 should support an API to retrieve query logs. This is particularly relevant
because HiveServer2 supports async execution but doesn't provide a way to report progress.
Providing an API to retrieve query logs will help report progress to the client.
