interesting. So demux is now part of the collector and does not need to be run as another job?
Since demux is doing basic ETL into hbase, is there a way to actually parse the fields of the log record and insert those into sep fields into Hbase to run mapreduce there (instead of the whole body as a field is what I think is happening) On Wed, Oct 26, 2011 at 12:59 AM, SALAMI Patrick <[email protected]>wrote: > Ok, thanks! > > -----Original Message----- > From: Eric Yang [mailto:[email protected]] On Behalf Of Eric Yang > Sent: Tuesday, October 25, 2011 6:19 PM > To: [email protected] > Subject: Re: Chukwa trunk does not write to HBase > > Demuxer for Chukwa 0.4 is a mapreduce job acting as ETL process to convert > the data into semi structure format for further processing.
