Subject [jira] [Created] (CRUNCH-608) HFile creation doesn't write Bloom filters
Date Tue, 10 May 2016 09:02:12 GMT
Gabriel Reid created CRUNCH-608:

             Summary: HFile creation doesn't write Bloom filters
                 Key: CRUNCH-608
             Project: Crunch
          Issue Type: Bug
            Reporter: Gabriel Reid
            Assignee: Gabriel Reid

The HFile writing logic in HFileOutputFormatForCrunch doesn't write Bloom filter data to the
created HFiles, even if bloom filters are enabled on the column family that is being written
(which is the default).

This means that the created HFiles may offer degraded performance (until they are replaced
via compaction) when searching for rows which don't exist in the given HFiles.
