IMPALA-5625: stress test: write profile when queries fail
This change writes query profiles as text files for all of the major
query failure reasons in the concurrent_select stress test.
1) Change the --result-hash-log-dir command-line option to --results-dir
and update the help text.
2) Introduce two new directories under the directory given by the
--results-dir command-line argument:
profiles
result_hashes
3) Move results into the result_hashes directory.
4) Write the query profile to the profiles directory when a query times
out or gets an error or incorrect results.
5) Remove the query profile from the log output for unexpected mem
limit exceeded exceptions. Instead, write those to the profiles
directory as well.
Testing:
Ran the stress test with a driver that changes the hashes of some of the
query results in the runtime info json file to inject incorrect result
failures. Set tight bounds on the mem limit and timeout to ensure there
would be timeouts and exceeded memory limit failures. Restarted the
NameNode mid test run to induce a query failure. That covers the 4 cases
for which an exception is thrown and profile is written for query
failures. Verified that the profiles were written for each kind of
query failure.
