Lars Hofhansl commented on HBASE-17877:
---------------------------------------
We could also flat-out use the Hadoop comparator - or for that matter even the
plain Guava comparator.
I do think, though, since this is do core to HBase that code should be part of
HBase and be changed by us, and not by a project we depend on.
Lemme make a new patch bringing back the change [~Apache9] points out - I
wonder whether that perhaps is the part that makes it slower in the one case
that [~vik.karma] found; and also leave the variables as final. The goal with
this was to simply pull the Hadoop code into HBase (and remove the extra Guava
dependency).
