Prasanth Jayachandran updated HIVE-9756:
----------------------------------------
Attachment: HIVE-9756.3.patch
[~sershe] Attaching rebased patch. Also updated the properties to use the new
configuration format. I haven't tested this patch extensively yet. This patch
creates new file per dag id. The file name format will be
<application_id_string>_dag_id_<dag_identifier>.log
There might be one more change required for this. Since MDC contexts are not
inheritable for the threads created using thread pools, in TaskRunnerCallable
we might need to pass a custom executor service that clones the MDC in
beforeExecute() hook of thread pool. Alternatively, we can change
CallableWithNdc so that it clones the MDC as well.
> LLAP: use log4j 2 for llap (log to separate files, etc.)
