> 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
> Priority: Critical
> Labels: broken-build, flaky
>
> 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.
