> We found that the Configuration object in UGI in KMS server is not initialized properly,
therefore it does not load core-site.xml from {{KMSConfiguration.KMS_CONFIG_DIR}}.
> This becomes a problem when the Hadoop cluster uses LdapGroupsMapping for group resolution,
because the UGI in KMS falls back to the default JniBasedUnixGroupsMappingWithFallback (defined
in core-default.xml) and is thus not consistent with the Hadoop cluster.
