             Summary: Clarify order of arguments to single_node_perf_run.py
                 Key: IMPALA-6150
                 URL: https://issues.apache.org/jira/browse/IMPALA-6150
             Project: IMPALA
          Issue Type: Improvement
          Components: Infrastructure
    Affects Versions: Impala 2.11.0
            Reporter: Tim Armstrong
            Assignee: Jim Apple


The script help doesn't specify which of the hashes is the reference and which is the baseline, which makes it hard to interpret the output of the run. I'm not sure but I think I may have been interpreting the order backwards. Can we clarify this in the help?

{noformat}
$ ./bin/single_node_perf_run.py --help
Usage: 
single_node_perf_run.py [options] git_hash_A [git_hash_B]

When one hash is given, measures the performance on the specified workloads.
When two hashes are given, compares their performance. Output is in
$IMPALA_HOME/perf_results/latest.

WARNING: This script will run git checkout. You should not touch the tree
while the script is running. You should start the script from a clean git
tree.

WARNING: When --load is used, this script calls load_data.py which can
overwrite your TPC-H and TPC-DS data.
