> Session is critical for a multi-user system like Hive. Currently Hive doesn't
> log seessionId to the log file, which sometimes make debugging and analysis
> difficult when multiple activities are going on at the same time and the log
> from different sessions are mixed together.
> Currently, Hive already has the sessionId saved in SessionState and also
> there is another sessionId in SessionHandle (Seems not used and I'm still
> looking to understand it). Generally we should have one sessionId from the
> beginning in the client side and server side. Seems we have some work on that
> side first.
> The sessionId then can be added to log4j supported mapped diagnostic context
> (MDC) and can be configured to output to log file through the log4j property.
> MDC is per thread, so we need to add sessionId to the HS2 main thread and
> then it will be inherited by the child threads.
