Subject Re: Hadoop upgrade from 2.5.1 to 2.7.3 (Running Hbase 1.2.5)
Date Fri, 28 Jul 2017 17:30:37 GMT
Take a look at the 2.7.3 docs on rolling upgrade for HDFS:

http://hadoop.apache.org/docs/r2.7.3/hadoop-project-dist/hadoop-hdfs/HdfsRollingUpgrade.html

I don't think there's similar existing docs for YARN, but your cluster
description sounds like you're only using HDFS anyways.
