Subject: Re: mapreduce from cassandra to cassandra
BTW, maybe we should create an issue on jira for this problem if the
Cassandra committee think it is necessary.

reuse is not possible, but I think it won't hard for cassandra to
implement a ColumnFamilyOutputFormat. In my opinion, the
ColumnFamilyOutputFormat should be easier to implement than
ColumnFamilyInputFormat, because you don't need to think about split
in the implementation of OutputFormat.
On
hbase - yes. But is that reusable for cassandra?

I believe it is possible to write result back to cassandra. If I
remember correctly, HBase has both InputFormat and OutputFormat for
hadoop.

In the wordcount example the process reads from cassandra and the result is
written to a local file at /tmp/word_count*
Is it possible to read from cassandra and write the result back to cassandra
to a specified cf/row/column?
I see that there exists a ColumnFamilyInputFormat but not
ColumnFamilyO
