------------------------------------
Summary: NPE when Scan's stopRow is set NULL
Key: HBASE-16498
URL: https://issues.apache.org/jira/browse/HBASE-16498
Project: HBase
Issue Type: Bug
Components: Client
Reporter: Pankaj Kumar
Assignee: Pankaj Kumar
Priority: Minor
During scan operation we validate whether this is the last region of table, if
not then records will be retrieved from nextscanner. If stop row is set null
then NPE will be thrown while validating stop row with region endkey.
