Subject Re: [DISCUSSION] Making HBaseWriter default
Date Mon, 22 Nov 2010 18:50:56 GMT
I agree with Bill and Deshpande that we ought to make clear to users
that they don't nee HICC, and therefore don't need either MySQL or

But I think what Eric meant to ask was which of MySQL and HBase ought
to be the default *for HICC*.  My sense is that the HBase support
isn't quite mature enough, but it's getting there.

I think HBase is ultimately the way to go. I think we might benefit as
a community by doing a 0.5 release first, while waiting for the
pig-based aggregation support that's blocking HBase.

up, I don't need HDFS. I am using Chukwa merely as a Log Streaming framework. I have plugged
in my own writer to write log files in Local File system (instead of HDFS). I evaluated Chukwa
with other frameworks and Chukwa had very good fault tolerance built in than other frameworks.
This made me recommend Chukwa over other frameworks.
