Gabriel Reid updated CRUNCH-608:
--------------------------------
Attachment: CRUNCH-608.patch
Patch to use a correctly-configured StoreFile.Writer (instead of HFile.Writer)
for writing HFiles. The StoreFile.Writer includes the necessary logic for
writing Bloom filters within HFiles.
Also includes an addition to existing integration tests to verify that the
bloom filter data is written.
> HFile creation doesn't write Bloom filters

>
> 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.
