http://gerrit.cloudera.org:8080/#/c/20181/4/tests/query_test/test_hive_codec_interop.py
File tests/query_test/test_hive_codec_interop.py:

http://gerrit.cloudera.org:8080/#/c/20181/4/tests/query_test/test_hive_codec_interop.py@a61
PS4, Line 61:     source_table = "{0}.{1}".format(unique_database, "t1_source")
This tested that Hive could read a textfile written by Impala. But it didn't 
test any particular compression, so that didn't seem very useful.


http://gerrit.cloudera.org:8080/#/c/20181/4/tests/query_test/test_hive_codec_interop.py@50
PS4, Line 50: ImpalaTestSuite
> TestFileCodecInterop?
That makes more sense. I misunderstood the super call, and calling 
super(TestFileCodecInterop, cls).add_test_dimensions fails because it's not 
defined on ImpalaTestSuite. Not sure why this one works.

PS4, Line 68:
> nit. unnecessary newline?
I liked the formatting better, but I can remove it.

Ah, I misunderstood this call.
