> 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 was 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.
