Hi,

HCP : 1.3.0  / Metron :  0.4.1.1

HDP : 2.5.0


Kerberos Authentication enabled for Hadoop cluster.

When Metron Rest trying to connect to Storm, error is thrown as no Server
not found in Kerberos database (7) - LOOKING_UP_SERVER

>>>KRBError: cTime is Thu Oct 28 12:56:54 AEST 1971 57466614000 sTime is

In KDC there is no principal with
HTTPS/[email protected]

We can see only
*HTTP/[email protected]
<HTTP/[email protected]>*

If we add manually principal (
HTTPS/[email protected]) using kadmin in
kerberos server, getting error as checksum failed
