Hi Team, Currently I'm running Hadoop 1.2.1 in CentOS 6, I would like to Upgrade from 1.x version to 2.x version which has High Availability and YARN, etc. I'm not finding any Exact Guide for the same, could you please help/guide me for the Upgrade. Note: I'm not using any Management Tools like Ambari or Cloudera, I would like to do it manually. Please help me.
Thanks, Santhosh R.
