Jean-Marc Spaggiari commented on HBASE-7503:
--------------------------------------------

Thanks for the comments/review.

Is the end key = next region start key? If so then yes it should be <. But I 
tought the end key of a region was lower than the start key of the next region. 
This surprised me I agree because I know we only store the start key for a 
region...

I will apply those comments shortly:
qt. Map<Get, Integer> reference = new HashMap<Get, Integer>();
qt. needs better name.

qt. LOG.debug("Failed for gets on region: " + sortedGetEntry.getKey());
qt. warn, like below?

qt. testHTableExists
qt. Misleading name too.

qt. I'd split the test into smaller tests too (approximately on comment 
boundaries ) but that's a matter of personal preference.

I will also rename "references". 

I'm not sure for the comment about "While mapping..." and "Maybe it's possible 
to have array, ..." I will have to read them again to make sure I get the 
suggestion correctly.
