The data stored in Hadoop after the demux process is a sequence file
containing the data. One easy way to get this is to use Pig via the
Note that it's using the SequenceFileRecordReader like this to read the
data, so if you don't want to use Pig, you could do something similar.
The ChukwaRecord contains a handful of fields created by the Processor that
you've configured to collect your data. If you're using the TSProcessor, I
think the payload is in a field called 'body' IIRC.
There's also a command line java tool to dump the contents of a sequence
file to stdout, which can be handy. I forget what it's called, but it
should be in the docs.
