Description

As part of HBase 1.2.x when PXF connects to hbase we see the following error due to the missing metrics-core jar.

SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container

This jar needs to be added to the pxf-private classpath file
