Description

RouterClientProtocol#getMountPointStatus logs error when groups are not found for default web user dr.who. The line should be logged in "error" mode for secured cluster, for unsecured clusters, we may want to just specify "debug" or else logs are filled up with this non-critical line

ERROR org.apache.hadoop.hdfs.server.federation.router.RouterRpcServer: Cannot get the remote user: There is no primary group for UGI dr.who (auth:SIMPLE)
