---------------------------------------
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.
