Cassandra 2.0 with Hadoop 2.x?
Folks,
Has anyone out there used Cassandra 2.0 with Hadoop 2.x? I saw this
discussion on the Cassandra JIRA:
https://issues.apache.org/jira/browse/CASSANDRA-5201
but the fix (https://github.com/michaelsembwever/cassandra-hadoop)
referenced in the thread is for Cassandra 1.2.
I put together a similar patch for Cassandra 2.0 for anyone who is interested:
https://github.com/wibiclint/cassandra2-hadoop2
but I'm wondering if there is a more official solution to this
problem. Any help would be appreciated. Thanks!
Best regards,
Clint

Clint, I'm hoping that
https://issues.apache.org/jira/browse/CASSANDRA-5201 will
make it into Cassandra 2.0, as it is a general purpose solution that will
work for both mapred, and mapreduce based code.

One other question: Has anyone considered taking a crack at modifying
the CqlPagingRecordReader to use the DataStax java driver? I am not
sure how that kind of cross-pollination of different projects works,
but I thought the paging mechanisms in the DataStax driver might help
simplify the CqlPagingRecordReader code.
