--------------------------------------
[~pvary]
Regarding the lines "TOTAL_TABLE_ROWS_WRITTEN" and "CREATED_FILES" in
rfc5424_parser_file_pruning.q.out I wasn't sure either. I've run the following
in the latest upstream master branch:
{code:java}
mvn test -Dtest=TestMiniLlapLocalCliDriver
-Dqfile=rfc5424_parser_file_pruning.q
{code}
and it fails. Not sure if this shows up in current precommits or not.
> Make sure qtests clean up copied files from test directories

>
> Several qtest files are copying schema or test files to the test directories
> (such as ${system:test.tmp.dir} and
> ${hiveconf:hive.metastore.warehouse.dir}), many times without changing the
> name of the copied file. When the same files is copied by another qtest to
> the same directory the copy and hence the test fails. This can lead to flaky
> tests when any two of these qtests gets scheduled to the same batch.
>
> In order to avoid these failures, we should make sure the files copied to the
> test dirs have unique names and we should make sure these files are cleaned
> up by the same qtest files that copies the file.
