Date Thu, 20 Aug 2015 02:15:47 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12061?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Akira AJISAKA updated HADOOP-12061:
-----------------------------------
    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

Committed this to trunk and branch-2. I've committed this to branch-2.7 as well because the
patch is to fix the documentation and the risk is very low. Thanks [~sekikn] for the contribution!

> There seems to be a trivial fault in the single node cluster setup document on branch-2.
> "Setup passphraseless ssh" says as follows:
> {code}
>       $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
>       $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
>       $ export HADOOP\_PREFIX=/usr/local/hadoop

> But it should be:
> {code}
>       $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
>       $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
>       $ chmod 0700 ~/.ssh/authorized_keys
> {code}
