Joydeep Sen Sarma commented on HIVE-1464:
-----------------------------------------
i think i found why it's happening.
these lines in build-common.xml:
<copy todir="${test.data.dir}">
<fileset dir="${test.src.data.dir}">
<exclude name="**/.svn"/>
</fileset>
</copy>
are copying .gitignore to test/data/warehouse/src
it remains there after this. the reason this is happening now is that
'cleanup()' happens via metadata commands - and there are no tables in metadata
at the beginning of the test. so nothing gets deleted. then a whole bunch of
'load data' commands are executed - which also don't delete old stuff.
after this - earlier each test would call cleanup() again - which would delete
the entire directory. but now this is not done anymore. so the .gitignore stays
there.
lots of ways of fixing this - but this whole data/warehouse dir and then
copying it recursively is totally unnecessary i think. i will file a separate
jira.

> clientpositive/negative tests are extremely slow.
> one major problem seems to be that all the test warehouse tables are deleted
> and created/re-populated for each test. most of the times this is not
> required and if we can fix this the tests will run much faster.
