Subject [jira] [Created] (HADOOP-12061) Incorrect command in 2.7.0 single cluster setup document
Date Thu, 04 Jun 2015 14:29:38 GMT
Kengo Seki created HADOOP-12061:
-----------------------------------

             Summary: Incorrect command in 2.7.0 single cluster setup document
                 Key: HADOOP-12061
                 URL: https://issues.apache.org/jira/browse/HADOOP-12061
             Project: Hadoop Common
          Issue Type: Bug
          Components: documentation
    Affects Versions: 2.7.0
            Reporter: Kengo Seki
            Priority: Minor


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
{code}

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}
