Subject Hive Storage Handler for Cassandra
Date Mon, 16 Aug 2010 17:07:36 GMT
Hello,

Anyone interested in doing map/reduce on Cassandra data should take a
look at Cassandra Storage Handler for Hive. Storage handlers give Hive
the ability to work with data outside HDFS in a more natural way.
Support is now in place for reading and writing to/from Standard
Column Families (no super column support yet). While this allows users
to use an SQL like language on their Cassandra data, it does NOT do
things like push down of a where clause into sub-second queries.

https://issues.apache.org/jira/browse/HIVE-1434

For those looking to try this out with minimal effort, I have a tar
bundle with cassandra, hive, and hadoop here:

::Warning::
The bundle is a pre-release build of Hive with cassandra support.
Treat it as such.

Enjoy,
Edward
