Description

UpgradeCatalog220#updateKerberosDescriptorArtifact

            KerberosIdentityDescriptor hdfsIdentity = hdfsService.getIdentity("hdfs");
            KerberosComponentDescriptor namenodeComponent = hdfsService.getComponent("NAMENODE");
            hdfsIdentity.setName("hdfs");
            hdfsService.removeIdentity("hdfs");

in case of second run on same database we will have here NPE, coz that descriptor was already removed. Before using him, we need check that descriptor is present and is not null
