Avoid Kerberos logging multiple times as it may cause race condition problems

Weird behaviour has been detected after the ticket expired when multiple logins to kerberos are triggered from different HBase modules in the TSO. The result is that the Kerberos ticket is not renewed and it causing this exception to be thrown:
