---------------------------------------------------------------
One solution would be to implement a TextColumnFamilyInputFormat that wraps
ColumnFamilyInputFormat to convert the datastructures it outputs into
JSON/TSV/CSV.
EDIT: Actually, rather than Text based serialization, wrapping the data
structure in Avro/Thrift structs might be much more performant.

> Make hadoop functionality available to languages other than Java

> Key: CASSANDRA-1193
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1193
> Project: Cassandra
> Issue Type: Improvement
> Components: Hadoop
> Reporter: Jeremy Hanna
> Priority: Minor
>
> Currently the hadoop functionality, specifically the MapReduce hooks that are
> in Cassandra, are only available via Java code.
> It would be nice to make that functionality available to other languages,
> perhaps via hadoop streaming. This allows any language that can use
> STDIN/STDOUT to use MapReduce.
> It seems like this approach could be realized with a small amount of code to
> make the inputs/outputs into strings.
