Description

Impala currently uses log4j for logging. log4j has reached end of life and is not maintained. We need to migrate to using log4j2 for Impala's logging.

Currently, it looks like we hook up log4j to log to glog through the GlogAppender:

There may be configuration changes for the minicluster as well.
