Before this patch the message was added to the profile in Open(), which can be called multiple times in subplans. Moved it to Close(), which is only called once in the lifetime of a Node/Aggregator. A drawback of this is that this info won't be visible when the Node is still active, but I don't think that it is a very useful info in a still running query. Also added a new feature to test_result_verifier.py: Inside RUNTIME_PROFILE section row_regex can be negated with !, so !row_regex [regex] means that regex is not matched by any line in the profile. Testing: - added a regression test Change-Id: Iad2e31900ee6d29385cc8adc6bbf067d91f6450f Reviewed-on: http://gerrit.cloudera.org:8080/18385 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
