--------------------------------------------
Summary: Modify Ranger Hbase Plugin ColumnIterator to use Cell
instead of KeyValue (to avoid ClassCastException in certain cases)
Key: RANGER-1365
URL: https://issues.apache.org/jira/browse/RANGER-1365
Project: Ranger
Issue Type: Bug
Components: plugins, Ranger
Affects Versions: 0.7.0
Reporter: Sergio Peleato
Priority: Critical
Fix For: 0.7.0
[RangerAuthorizationCoprocessor|https://github.com/apache/ranger/blob/7a1c72262684a862f8df4ba908c5a2a918cb1f53/hbase-agent/src/main/java/org/apache/ranger/authorization/hbase/RangerAuthorizationCoprocessor.java#L1029]
and
[ColumnIterator|https://github.com/apache/ranger/blob/eb21ea6afb9f2ca0e26a769bfc6333ba3cce0e61/hbase-agent/src/main/java/org/apache/ranger/authorization/hbase/ColumnIterator.java#L76]
need to be modified to safely cast objects into Cell rather than KeyValue as
currently done.
In certain cases, the above issue causes HBase regionserver to throw the below
exception.
