Ted Yu commented on HBASE-12915:
--------------------------------

Integrated to branch-1.0 +

Got compilation error in hbase-server/src/main/java/org/apache/hadoop/hbase/snapshot/CreateSnapshot.java
in 0.98

Will integrate to 0.98 once compilation issue is fixed.

> If user sets batching in Scan object, ClientSmallScanner may return unexpected result
because data from same row may appear in multiple Result objects but ClientSmallScanner considers
different Results to correspond to different rows.
> Small scan with batching should be disallowed.
