HBQL queries HBase directly, but it's not SQL-compliant and doesn't feature relational keywords (since HBase doesn't support them, JOINs don't scale). I don't know if anybody tried integrating HBQL in Hibernate... it's still a very young project. > > Q2> Once the data is in there in Hbase.

Hive goes on top of HBase, so you can use its query language to mine HBase tables. Be aware that a MapReduce job isn't meant for live queries, so issuing them from Hibernate doesn't make much sense... unless you meant something else and this which case please do give more details. > > Thanks & Regards > Amit Kumar >
