Cannot Open Knox Gateway Keystore

Cannot Open Knox Gateway Keystore

Explorer

I'm in the process of renewing certificates in my HDP cluster and the last thing on the agenda is the Knox server.

 

I understand that the new node cert is to be imported into gateway.jks, the Knox keystore, with an alias "gateway-identity".

 

The problem is no one knows the password to the keystore. I thought it was the master secret, which to my understanding is contained in the master file, typically under /var/lib/knox/data/security/master.

 

So I copy the password string inside and try it with the keystore, and obviously it's not working. 

 

I really want to avoid creating a new master secret password (what would be the exact detailed implications or steps required after such an action anyways?)
