RE: DFS Permissions on Hadoop 2.x
I believe, the properties name should be "dfs.permissions"

Subject: DFS Permissions on Hadoop 2.x

Hello,

We just upgraded our cluster from 0.20.2 to 2.x (with HA) and had a question around disabling dfs permissions on the latter version. For some reason, setting the following config does not seem to work

<property>
        <name>dfs.permissions.enabled</name>
        <value>false</value>
</property>

Any other configs that might be needed for this?

Here is the stacktrace.
