Review request for hive.
Bugs: HIVE-13415
https://issues.apache.org/jira/browse/HIVE-13415
Repository: hive-git
Description
-------
Current behaviour is:
* Open a thrift binary transport
* create a session
* close the transport
Then the session gets closed. Consequently, all the operations running in the
session also get killed.
Whereas, if you open an HTTP transport, and close, the enclosing sessions are
not closed.
This seems like a bad design, having transport and sessions tightly coupled.
I'd like to fix this.
The issue that introduced it is
[HIVE-9601|https://github.com/apache/hive/commit/48bea00c48853459af64b4ca9bfdc3e821c4ed82]

and mentioned links on those comments.
Another thing that seems like a slightly bad design is this line of code in
ThriftBinaryCLIService:
{noformat}
server.setServerEventHandler(serverEventHandler);
{noformat}
Whereas serverEventHandler is defined by the base class, with no users except
one sub-class(ThriftBinaryCLIService), violating the separation of concerns.
