re-create keytab for Spark

[#1]

Hi,

 I have a kerberized cluster, where each application is working fine (hdfs, yarn, hive). Accidentally via kadmin.local I re-exported the keytab for the spark user.

xst -k .... 

And now the Clouder Manager of course complains because Spark cannot start, the keytab stored in CM database is different and does not match with the Kerberos DB.

So how to:

 - replace the keytab in Cloudera Manager database with the new one which I just created? or..

 - force Cloudera Manager to re-create keytab for the Spark application?

Thanks

T.

Hello Tomas79,

You can do so by going under Adminstration -> Security -> Kerberos Credentials -> Select the once that you would want to regenerate. 

Hope that helps.

I overlooked that option.
