-------------------------------------------------------------------
v02: The Configuration object is shared by both KMS client and server in unit
tests because UGI gets/sets it to a static variable. I don't see a way to
isolate client's configuration from server.
Fortunately, UGI-sensitive configuration names are independent between KMS
client and server. As a workaround, make sure the client configurations are
copied to the server's so that client can read them.

> KMS should set UGI's Configuration object properly

> 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.
