> The second message shown above is ambiguous, After reading the sentence below it looks
like that complete Hawq cluster in whole has only 98304 MB and 12 cores. However according
to the configuration it should be 98304 MB and 12 cores per segment server.
> {code}
> Resource manager YARN resource broker counted HAWQ cluster now having (98304 MB, 12.000000
CORE) in a YARN cluster of total resource (1376256 MB, 168.000000 CORE).
> {code}
> Either the wrong variables are printed or we can correct the message to represent that
the resources logged are per node. As this can confuse the user into thinking that hawq cluster
does not have enough resources.
