stack commented on HBASE-17877:
-------------------------------
bq. The main difference in the two versions is related to the binary search
using the diff between the longs being compared in Hadoop version Vs doing
Long.reverseBytes and then comparing in HBase version.
We only do the binary search if we are NOT bigendian yet java is bigendian? I'm
misreading? Thanks.
> Replace/improve HBase's byte[] comparator
