> 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.
