Rajeshbabu Chintaguntla updated PHOENIX-2665:
---------------------------------------------
Attachment: PHOENIX-2665.patch
[~jamestaylor]
Here is the patch fixes three issues
1) Currently when we get stale region exception we might set wrong boundaries
for the scanner because hbase client can change the scan start key.
2) BaseResultIterators#getParallelScans is generating scans not in the range of
startkey, endkey passed.
3) When there split of a table with single region we are continue with scanning
single scanner even though scan boundaries not in the region range.
Please review.
