> Tez currently uses CallableWithNdc to store thread specific context. It
> should also inject the context into MDC so that pattern layout can dump the
> contexts from MDC (with NDC it is not possible to read the context in pattern
> lyaout).
> Hive for example, sets queryId in the MDC and pattern layout prints the
> queryId
>
> {code:java}
> %d{ISO8601} %-5p [%t (%X{queryId})] %c{2}: %m%n
> {code}
> Llap sets dagId, fragmentId and queryId into MDC which is used for queryId
> based routing of logging.
> Similarly, Tez AM should set dagId and queryId (if available) into MDC.
