Enable Tracing in AWS EMR

[cmbendre <ch...@zeotap.com>]

Hi,

I am trying to run pherf-cluster.py on AWS EMR with Hadoop - 2.7.1 + HBase -
1.3 + Phoenix 4.9.

I am able to run pherf-standalone.py but pherf-cluster.py fails with
following error - 

/Exception in thread "main" java.lang.AbstractMethodError:

This error seems related to tracing and some missing configurations on
region-server from what i can understand. Please help.

Thanks
Chaitanya
