Description

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.
