Using Hadoop for MapReduce on Cassandra?

From: Alex M.
Sent on: Friday, May 9, 2014 3:38 PM
So - I am seeing a lot of interest in Apache Cassandra for BigData databases....I am interested to learn more about how Apache Cassandra differs from HBase. It seems to be that Cassandra is *eventually* consistent, whereas HBase is more ACID compliant. 

It seems that users who already have a Hadoop cluster use HBase, but those who don't often pick Cassandra first. 

I note that you can set up FlumeNG to write Hadoop events to Cassandra, but I am more interested in the other way. Has anyone in HUGUK actually done MapReduce/Hive operations reading from Cassandra instead of HDFS. 


PS. This mailing list is supposed to be for discussion between HUGUK members so that we can share our knowledge and experience. I know it is mostly used for announcements, but it isn't limited to that.
