Subject HA Hadoop journal nodes configuration
Date Thu, 08 Jan 2015 04:00:02 GMT

I want to setup Hadoop HA with 2 NameNodes and journal nodes. But I am not
sure what should be the configuration of journal nodes

1. How many journal nodes I need
2. What should be the machine configuration like RAM, disk size etc

This is for a fairly small cluster dealing with 20 Terabytes of data.
