Extending the CDH cluster with BDA software version 2.3.1 fails running step 2:

The following succeeds creating the mammoth-params file:

[root@bdanode01 BDAMammoth]# ./mammoth -e bdanode07 3

SUCCESS: Successfully generated parameter file mammoth-<RACK_NAME>-1.params

However the following error is seen while running step 2 of the mammoth installation:

[root@bdanode01 BDAMammoth]# ./mammoth -s 2
INFO: Logging all actions in /opt/oracle/BDAMammoth/bdaconfig/tmp/STEP-02-20140122192620.log and traces in /opt/oracle/BDAMammoth/bdaconfig/tmp/STEP-02-20140122192620.trc

ERROR: An Appliance of name <RACK_NAME> has already been installed.

INFO: Time spent in step 2 SetupPuppet is 0 seconds.

The trace shows that it failed at step 2:

# cat /opt/oracle/BDAMammoth/bdaconfig/tmp/STEP-02-20140122192646.trc
