"expecting X results" spam

[Jean-Daniel Cryans]

Hey devs,

I was testing out 0.92 and HCM got this like this a year ago:

+      if (LOG.isDebugEnabled()) {
+        LOG.debug("expecting "+results.length+" results");
+      }

coming from HBASE-2002 (it's triggered for every processBatchCallback). Was
it intentional? It sure is at DEBUG but since we ship at that logging level
I would suggest removing it.
