[jira] [Commented] (HADOOP-12565) Setup passphraseless SSH does not work on all systems

    [ https://issues.apache.org/jira/browse/HADOOP-12565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15020754#comment-15020754 ] 

Mingliang Liu commented on HADOOP-12565:
----------------------------------------

Is it OK by not suggesting the type of key to create? I think the default one will work just fine.

> 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.
