Subject [jira] [Commented] (CASSANDRA-15782) Compression test failure
Date Mon, 04 May 2020 17:43:00 GMT


Joey Lynch commented on CASSANDRA-15782:

[~Bereng] If you are referring to the test_compression_cql_options - compression_test.TestCompression
test failing
with the following stack trace:
        for sstable_path in sstable_paths:
            sstable = os.path.join(sstable_path, sstables['compression_opts_table'][1])
            if os.path.exists(sstable):
>               assert 'DEFLATE' == self._get_compression_type(sstable)
E               AssertionError: assert 'DEFLATE' == 'UNKNOWN'
E                 - DEFLATE
E                 + UNKNOWN

Yeah that looks like my patch, I thought I ran the dtests but guess I missed the cqlsh dtests
(oops). This is an expected change in behavior (deflate should flush with lz4 now and then
compact to deflate). I think an easy fix to the test would be to compact after the flush.
I can fix it.
