Subject Re: New Production Cluster Criticisms/Advice
Date Wed, 15 Aug 2012 02:42:00 GMT
Real clusters are a tad harder than the pseudo cluster.

You may want to consider EMR where you can choose between Amazon's Hadoop release (Its Apache),
MapR M3 or MapR M5

It's a dataflow language that makes analytics really easy.

Basically, just logging a ton of information I might want for analytics/model training later.

I'm not married to this, and haven't played around much with hbase yet, but wanted to leave
the possibility open.

there, and I really like the option to be able to spin up a bunch of extra workers at will
to have them train some ML model for me and then kill them off. For now, just to get things
off the ground, I'm going to setup a small 4 machine cluster (1 NameNode, 1 SecondaryNameNode/JobTracker,
2 DataNode/TaskTrackers). I'll start playing around with that setup, and will add more to
it as needed. Since everything will be puppetized, adding more machines shouldn't be too bad
(I think). I've been using Cloudera so far, and I haven't seen any good reason to switch,
so I'll use CDH4. For logging, I'll just use scribe and wind up storing stuff as lzos (a good
tutorial on the best way to do this would be awesome).
