Zoltán Borók-Nagy commented on IMPALA-9451:
-------------------------------------------
Seems like it fails because in the minicluster environment Hive3 CTAS is
broken, it doesn't write any data.
{noformat}
CREATE TABLE copy_tbl AS SELECT * FROM source_table;
SELECT count(*) FROM copy_tbl;
0
{noformat}
Hive2 CTAS works fine.
Before this test we didn't use Hive CTAS in our tests, so it's hard to tell
since when it is broken.
The issue also occurs with newer versions of CDP Hive (I've seen it in builds
where CDP_HIVE_VERSION was 3.1.3000.7.1.1.0-288).
Seems like the bug is specific to the Impala minicluster environment, i.e. it
doesn't appear in other deployments of Hive.
