------------------------------------------
Summary: Tez should inject dag id, query id into MDC
Key: TEZ-4039
URL: https://issues.apache.org/jira/browse/TEZ-4039
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.9.next
Reporter: Prasanth Jayachandran
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.
