Lars Hofhansl updated HBASE-17877:
----------------------------------
Attachment: 17877-v2-1.3.patch
Slightly different patch. Just retains some working variables as final.
If it wasn't before now {{i < minWords * SIZEOF_LONG}} is definitely optimized
out of the loop, since minWords is final.
> Replace/improve HBase's byte[] comparator
