Commit dc313b3e4cae3dd57c55cc40e9c2b824082918a7 in impala's branch
refs/heads/master from Amogh Margoor

IMPALA-10921 Add script to compare TPCDS runs.
This script compares 2 runs of TPCDS by parsing their respective
Impala plain text query profiles. It currently outputs the peak
memory comparision of both runs where:
1. It compares average per-node peak memory and geo-mean
per-node peak memory.
2. It compares max peak memory reduction among Hash operators.
It can be extended to other comparisions in future.
Example usage:
tpcds_run_comparator.py <path to base run profile>
<path to new run profile> [path to result csv file]
