> Hadoop (2.7), which is using Commons-logging is not compatible with log4j2 without bridge.

> The bridge is missing in Hive. 
> This leads to a problem whereby commons-logging initialises a log4j (1.2) version Logger,
does not configure it properly since configuration for it is missing and sends logging output
to stdout (the default).
