Hortonworks Data Platform 2.0 (Alpha)

And I choose HDP. Note: This bug practically means that using RCFILE is useless with hive-0.9.0. The column pruning is not used by hive at all. Now it seems that the problem is in HIVE-0.9.0. Unfortunately there is a bug also in HDP 2.0. This is not so serious however. When Ambari is  used for automated installation it can fail with  "Oozie test Fails" or if Oozie is not selected than with "Hive/HCatalog test Fails" message and the deployment log will show the following error message:  "\"Sun Mar 03 21:38:03 +0100 2013 /Stage[2]/Hdp2-hive::Hive::Service_check/Exec[/tmp/hiveSmoke.sh]/returns (notice): FAILED: Hive Internal Error: org.apache.hadoop.hive.ql.metadata.HiveException(MetaException(message:Could not connect to meta store using any of the URIs provide
