@mohammad_shamim 

You might be hitting a known bug with Java recent versions (OpenJDK 1.8u242 or JDK 11.0.6). TSB-394. 

 

To resolve this issue, take the following action on all impacted nodes solved as appropriate for the environment.

  1. Edit java.security file located in the active JDK on the clusters.
  2. Add or alter sun.security.krb5.disableReferrals parameter, to ensure that the following is set to true:
    sun.security.krb5.disableReferrals=true

     


Cheers!
