Subject SASL issue with Zookeeper cluster
Date Mon, 19 Oct 2015 08:56:34 GMT
Hi All,
I have a zookeeper cluster configured with Kafka without any SASL security configuration.
Also I have a hadoop cluster configured with security which uses a different zookeeper cluster.
So overall, I have two zookeeper clusters - one with security and one without security.

Now when I try to run a mapreduce program to fetch data from Kafka using non-secure zookeeper,
I get following error message of SASL though my read zookeeper cluster does not have security
configured.

I did try setting up parameter -Djava.security.auth.login.config=none while trying to run
the mapreduce program.

Any thoughts on how I can get rid of this security warning?
Regards,Sagar
