Using Rhadoop ,rmr ,Hive

[Sarvesh Jain]

 Rhbase doesnt support SQL query like group by. I came across a solution i.e. HIVE.
My question is can I use HIVE with rmr package? Input to map using hive and writing reduce result to Hive.
I found a RHive package (Link attached). Is this Rhive package compatible with rmr?

Because  hbase doesn't.

No, but there is a format to read the default hive format, so you can do some work with one and some with the other.

 

Input to map using hive and writing reduce result to Hive.

As far as using SQL, this doesn't help. As far as doing IO to a table, yes, you need to use an external table and the pig.hive format in rmr2.

Not that I know of
