Data loss prevention for disabling the Kerberos security on Hbase

[ Edited ]

Hi there!

We're about to turn on the Kerberos security on the production Hadoop system.

But there's a couple warnings about issues with disabling of such security on the production Hbase.

https://www.cloudera.com/documentation/enterprise/5-13-x/topics/cdh_sg_hbase_authorization.html

 

We would like to have a rollback option for the Hbase production system without Data loss.

In my mind this is an option to enable/disble Kerberos security on the production Hbase system without Data loss.

 

Is it possible ? If any manuals or how-to's about pitfalls ?

Maybe someone have already faced those issues or solved it ? 

 

Best regards, Sergio.

Re: Data loss prevention for disabling the Kerberos security on Hbase

The link you have provided refers to possible data loss in case of disabling security but it is in "authorization" part of security.

Enabling/disabling Kerberos is in the scope of "authentication". Personally I have done it to enable/disable with no data loss. There is no reason to lose data.

But if you have defined authorization rules, then it is diferent.
