BI tool for Hive-Hadoop

[Adarsh Sharma]

Dear all,
As all us know that Hadoop-Hive rocks the current Data Warehouse Market.
From the last few weeks I  am researching on some BI tools ( Pentaho, 
SpagoBI ) for Hadoop -Hive Warehouse.

Can Someone have any idea or experience to use open-sourced BI tool for 
Hadoop-Hive  Warehouse. Which one is best ?
Any help about Integration Steps would be appreciated.

Thanks in Advance
