Istvan Toth updated PHOENIX-6658:
---------------------------------
Description:
HBASE-26036 made a change where Region.get() always clones Off-Heap cells
before returning them.
In HBase all non-test occurances of this code were changed to create their own
RegionScanner to avoid copying the off-heap cells. We should do the same.
This would also let Phoenix run correctly with HBase 2.4.5-2.4.10 , as the fix
in HBASE-26036 introduced another bug, HBASE-26777, which causes failures in
Phoenix.
Without this change, Phoenix needs at least HBase version 2.4.11, that has the
fix for HBASE-26777.

This would also let Phoenix run correctly with HBase 2.4.5-2.4.9 , as the fix
in HBASE-26036 introduced another bug, HBASE-26777, which causes failures in
Phoenix.
Without this change, Phoenix needs an HBase version that has the fix for
HBASE-26777 (Hopefully 2.4.10 or 2.4.11).
