Subject Re: Dumping Cassandra into Hadoop
Date Tue, 19 Oct 2010 17:55:59 GMT
Depends on what you mean by dumping into Hadoop. 

If you want to read them from a Hadoop Job then you can use either native Hadoop or Pig. See
the contrib/word_count and contrib/pig examples. 

If you want to copy the data into a Hadoop File System install then I guess almost anything
that can read from Cassandra and create a file should be OK. You can then copy it onto the
HFS and read from there. 

Hope that helps.
