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.
