Prasanth Jayachandran updated HIVE-9756:
----------------------------------------
    Attachment: HIVE-9756.2.patch

[~sershe] You are right. In the context of threadpool we need to similar thing like CallableWithNdc
but for MDC. Only MDC's can be referred in routing appender and in log42j configs. I added
that back in this patch. Do you remember what issue you had with MDC before?
