Subject [Impala-ASF-CR] IMPALA-4822: Implement dynamic log level changes
Date Thu, 16 Feb 2017 00:36:19 GMT
Bharath Vissapragada has uploaded a new patch set (#13).

Change subject: IMPALA-4822: Implement dynamic log level changes

IMPALA-4822: Implement dynamic log level changes

Very often we have to change the logging levels
of Impalads and Catalog server for debugging purposes.
Currently, there is no way to do that without a restart
of the daemons, which is not a viable option in production

This patch addresses this supportability gap by exposing
the ability to set dynamic logging levels using a simple
web endpoint on Impalad/Catalog/Statestore web pages.

This includes setting VLOG levels (equivalent to --v flag)
as well as setting log4j levels on the Frontend and the
Catalog JVMs.
