Subject Re: EC2 Elastic MapReduce HBase install recommendations
Date Thu, 09 May 2013 04:47:04 GMT
With respect to EMR, you can run HBase fairly easily.
You can't run MapR w HBase on EMR stick w Amazon's release.

And you can run it but you will want to know your tuning parameters up front when you instantiate
it.
