Alexander Veit created HADOOP-12565:
---------------------------------------

             Summary: Setup passphraseless SSH does not work on all systems
                 Key: HADOOP-12565
                 URL: https://issues.apache.org/jira/browse/HADOOP-12565
             Project: Hadoop Common
          Issue Type: Bug
          Components: documentation
    Affects Versions: 2.7.1
         Environment: Linux (Gentoo)
            Reporter: Alexander Veit
            Priority: Minor


http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html

suggests to create a DSA key to ssh to localhost. However DSA is going to be deprecated[1],
and ssh to localhost with DSA actually does not work on all systems. I suggest to replace
DSA with RSA, ECDSA, or ED25519.
