Subject RE: Chukwa trunk does not write to HBase
Date Tue, 25 Oct 2011 22:49:10 GMT
Also, while we are chatting, I was hoping to understand the role of the demuxer. I am assuming
that HICC pulls all of its data from HBase. If using HBase, is it still necessary to run the
demuxer? I didn't see any mention of it in the latest quick start guide.

Hadoop trunk will require a different configuration than the one described in the Quick_Start

1. Apply this patch: HADOOP-7436, and rebuild hadoop.
2. Copy enclosed in this message to HADOOP_CONF_DIR

Restart hadoop.  You might need to match the HBase table schema with the metrics emitted by
Hadoop metrics 2 framework.
Hope this helps.
