> While the scm address can be a host name (relative to the current search
> domain) if the om address is just a hostname and not a FQDN a NPE is thrown:
> {code}
> 10 │ OZONE-SITE.XML_ozone.om.address: "om-0.om"
> 11 │ OZONE-SITE.XML_ozone.scm.client.address: "scm-0.scm"
> 12 │ OZONE-SITE.XML_ozone.scm.names: "scm-0.scm"
> {code}
> {code}
> 2019-03-29 14:37:52 ERROR OzoneManager:865 - Failed to start the OzoneManager.
> java.lang.NullPointerException
> at
> org.apache.hadoop.ozone.om.OzoneManager.getSCMSignedCert(OzoneManager.java:1372)
> at
> org.apache.hadoop.ozone.om.OzoneManager.initializeSecurity(OzoneManager.java:1018)

> at org.apache.hadoop.ozone.om.OzoneManager.main(OzoneManager.java:859)
> {code}
> I don't know what is the right validation rule here, but I am pretty sure
> that NPE should be avoided and a meaningful error should be thrown. (and the
> behaviour should be the same for scm and om)
