             Summary: TestCompressedNonText.test_insensitivity_to_extension can fail due to wrong filename
                 Key: IMPALA-10062
                 URL: https://issues.apache.org/jira/browse/IMPALA-10062
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
    Affects Versions: Impala 4.0
            Reporter: Joe McDonnell


The fix for IMPALA-10005 added a new TestCompressedNonText test. It relies on Hive generating specific file names when writing these compressed tables (i.e. it expects a file named 000000_0). It looks like that is not guaranteed by dataload, which can lead to failures like this:
{noformat}
query_test/test_compressed_formats.py:142: in test_insensitivity_to_extension
    unique_database, 'tinytable', db_suffix, '000000_0', src_extension, ext)
query_test/test_compressed_formats.py:86: in _copy_and_query_compressed_file
    self.filesystem_client.copy(src_file, dest_file, overwrite=True)
util/hdfs_util.py:79: in copy
    self.hdfs_filesystem_client.copy(src, dst, overwrite)
util/hdfs_util.py:241: in copy
    '{0} copy failed: '.format(self.filesystem_type) + stderr + "; " + stdout
E   AssertionError: HDFS copy failed: cp: `/test-warehouse/tinytable_avro_snap/000000_0': No such file or directory
E   ;{noformat}
The file list shows that the filename is actually "/test-warehouse/tinytable_avro_snap/000000_1"

We should update the test to tolerate this. The actual base filename doesn't matter for this test.

I have seen this exactly once so far.
