I'm working on a proof of concept. I'm using Pentaho suite 5.0.2.
From the user console, I can connect to an Impala table with the Interactive Report option successfully.
However when I used the Dashboard option with the same data source, I'm getting an error on the front end of:
'Security error while executing chart. Contact your administrator.'

In the Pentaho BIServer log, the error indicates the host name of the connection is null:

2014-02-03 11:12:12,501 ERROR [org.pentaho.platform.util.logging.Logger] misc-java.lang.String: ConnectFactory.ERROR_0001 - Database connection could not be established to: org.apache.hadoop.hive.jdbc.HiveDriver jdbc:hive://null:21050/default
java.sql.SQLException: Could not establish connection to jdbc:hive://null:21050/default: java.net.UnknownHostException: null

Any help is greatly appreciated.
