Description

If HDFS Sentry Sync is being used you cannot alter a view without failure.

Example:

0: jdbc:hive2://localhost:10000/default> create or replace view jview as select * from j1;
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Unable to alter table. (state=08S01,code=1)

HMS Log:

2015-04-17 22:22:42,942 DEBUG org.apache.sentry.hdfs.MetastorePlugin: #### Creating HMS Path Update SeqNum : [36]

h : null]

The cause appears to be the fact that a null is being passed as part of paths update which will result in the NPE on the Thrift layer seen on HS2.
