I'm using the current Cloudera Quick Start VM. I've created an Hive table with some data. Then, I've created an external table with the Hive Storage Handler. I was able to populate the HBase table. However, while quering the Hive/HBase table, I got the following error (NullpointerException):
14/04/16 01:18:51 ERROR security.UserGroupInformation: PriviledgedActionException as:hbase (auth:SIMPLE) cause:BeeswaxException(message:java.io.IOException: java.lang.NullPointerException, log_context:3ecc8100-e8f8-40a0-916b-00fa5a9b6b11, handle:QueryHandle(id:3ecc8100-e8f8-40a0-916b-00fa5a9b6b11, log_context:3ecc8100-e8f8-40a0-916b-00fa5a9b6b11), SQLState: )

I embedded Guava, zookeeper, hbase and hive-hbase-handler JARs. I followed the instructions made in this tutorial: http://www.n10k.com/blog/hbase-via-hive-pt2/
I am using the current Cloudera-Quick-Start VM. Job and Task-Tracker logs as well as Beeswax logs are telling me nothing.
Do you have any ideas about what I am doing wrong?
I am thankfull for any advise!
Best regards, Lena
