We have configured Hadoop as high availability so that we can achieve automatic failover using Quorum Journal Manager. It is working fine as expected. But we are not sure how to configure resource manager in 2.6.0 version.

Resource manager is needed for running map reduce programs. We need the configuration steps for resource manager failover setup in Hadoop 2.6.0 between the name nodes.

I don't know about MapReduce. If you have multiple Resource Manager (one Active at a time) you need to set its logical names http://gethue.com/hadoop-tutorial-yarn-resource-manager-high-availability-ha-in-mr2/

However I am not sure if the logical names for rm1,rm2(...) will be the same. If anybody can confirm this?

It can be achieved in oozie by using "logicaljt" as job-tracker value in your workflow

  • I assume you have already configured properties in yarn-site.xml for multiple RMs http://hadoop.apache.org/docs/r2.5.2/hadoop-yarn/hadoop-yarn-site/ResourceManagerHA.html#Deployment – Rahul May 20 '15 at 12:23
