Hello,
I am trying to install Ranger on my new fresh HDP 2.2.
Things went alright until I tried to start ranger-hdfs-plugin.
When I run ./enable-hdfs-plugin.sh and restart hdfs, nothing seem to work
correctly. I don't see anything in "Ranger Admin Web interface -> Audit ->
Agents", I can't create HDFS repositories in the web interface, and a
simple 'hadoop fs -ls /' throws a NullPointerException.
In my namenode logs, I found what seems to be the explanation:
Execution of 'su -s /bin/bash - hdfs -c 'export
PATH=$PATH:/usr/hdp/current/hadoop-client/bin ; hdfs --config
/etc/hadoop/conf dfsadmin -safemode get' | grep 'Safe mode is OFF''
returned 1.
