File tests/metadata/test_partition_metadata.py:

http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@124
PS18, Line 124:     # Create three partitions where two of them point to the 
same location.
              :     self.filesystem_client.make_dir(TBL_NAME + '/p1')
              :     self.filesystem_client.make_dir(TBL_NAME + '/p2')
This looks wrong, because the directories made here will only be 
"same_loc_test/{p1,p2}" and not rooted at TBL_LOCATION. Are these lines needed?

And if they are needed, then they need to have a uniqueness to them, because as 
it stands, parallel tests will overwrite each other's directories in this spot. 
Include unique_database as part of the directory name to solve this problem.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@127
PS18, Line 127: execute
Here and elsewhere, there's a execute_query_expect_success() method you should 
consider instead for statements you expect always to succeed.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@163
PS18, Line 163: it's
Are we (Impala) in control of this message? It should be "its".


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@168
PS18, Line 168:     assert false
If we are here, then we never raised an exception. It would be polite to show 
the partition information as part of diagnostics when the test fails.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@177
PS18, Line 177: pytest.skip()
You can insert a reason here. It's mildly helpful to someone that happens to 
see this go by on a console.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@184
PS18, Line 184:     # Cleanup any existing data in the table directory.
              :     self.filesystem_client.delete_file_dir(TBL_NAME, 
recursive=True)
As before, I can't tell that this is needed.

As before, if needed, this can collide with tests that are using a directory of 
TBL_NAME in L125-126, assuming the pwd is the same.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@187
PS18, Line 187: execute
As before, execute_query_expect_success() in places where you expect success.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@191
PS18, Line 191:     # Create two partitions pointing to the same location.
              :     self.filesystem_client.make_dir(TBL_NAME + '/p1')
Same comment for L185 applies here.


http://gerrit.cloudera.org:8080/#/c/10543/18/tests/metadata/test_partition_metadata.py@202
PS18, Line 202:     hive_cmd = ("ALTER TABLE %s DROP PARTITION (j=1)" % 
FQ_TBL_NAME)
              :     call(["hive", "-e", hive_cmd])
You can use self.hive_client() instead.
