Disabling Kerberos

[#1]

Hi all,

We have a Kerberized cluster,but at the moment we would disable it.

How is it possible ?

I performed the following steps:

• Zookeeper -> enableSecurity (Enable Kerberos Authentication)-> false

• HDFS -> hadoop.security.authentication -> Simple
• HDFS -> hadoop.security.authorization -> false
• HDFS -> dfs.datanode.address -> from 1004 (for Kerberos) to 50010 (default)
• HDFS -> dfs.datanode.http.address  -> from 1006 (for Kerberos) to 50075 (default)
• HDFS -> Data Directory Permissions -> from 700 to 755

• HBASE -> hbase.security.authentication -> Simple
• HBASE -> hbase.security.authorization -> false

But when I start the cluster I have problems on Hue and Solr

Hue: It seems that Kerberos is still configured for Hue 

        -> The Kerberos Ticket Renewer is not running. How can i disable it? 

        ->  Impala e Oozie don't run from Hue

Solr:  

Caused by: java.io.IOException: Failed on local exception: java.io.IOException: Server asks us to fall back to SIMPLE auth, but this client is configured to only allow secure connections.;

I noticed that Hue and Solr run in secure mode. How can I disable them ?

Thanks

Hello Alessio,

I am facing the same problem could you please outline the steps you did for Yarn and Zookeeper.

Thanks

The link provided is now broken. Is there an update to it?

Try this one:

Have the same problem, but after clean and reinstall cluster (using parcels). Error appears when oozie java action wrties to HDFS (runs from HUE). Earlier on this cluster was Kerberos, and I cleand all (I hope) directories from previous installation.

Here is a detailed message:

Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.JavaMain], main() threw exception, java.io.IOException:

I have a similar problem wanted to turn off Kerberos, so did everythin (turn auth to simple, data node ports etc etc).
Now the cluster does not use Kerberos, HDFS and Hive and Impala works fine, BUT THE OPTION FOR ENABLE KERBEROS IS STILL GREYED
Any thoughts?
