Karan Mehta updated PHOENIX-4997:
---------------------------------
    Description: 
Phoenix MR over snapshots uses TableSnapshotResultIterator and SnapshotScanner 
classes for iterating/scanning over snapshots. They had been copied over from 
HBase classes TableSnapshotScanner and ClientSideRegionScanner classes and 
modified according to Phoenix requirements. This decision was taken since some 
of fields of these classes were private and hence it is not possible to reuse 
them. HBASE-8369 is the main Jira.

The framework had a bug which was fixed as part of HBASE-16011. However the fix 
was not ported to Phoenix and hence Phoenix MR over snapshots still continues 
to have it. This Jira is to fix that issue.
