Subject Re: Experiment with Chukwa trunk
Date Mon, 11 Oct 2010 23:31:02 GMT
For streaming data to Hbase 0.20.6, Hadoop 0.20 is required.  If you are
using the sequence file and mapreduce, then Hadoop 0.18+ should work fine.
I would like to move forward with map reduce on table instead of map reduce
on file to reduce data processing latency.  Hence, I am making Hbase a
required component for trunk for a full end to end deployment.  The setup
may sound difficult to do, but it is trivial to setup.  In the long run,
demux does not need to be a map reduce job, and demux will only get
optimized for incremental updates, when developers start to adopt the table
approach.  Considering this migration as planning for a better future.  :)
For now, the existing Chukwa 0.4 approach is still works in trunk but I am
not enhancing the batch model.
