Only require both hbase.rootdir and hbase.zookeeper.quorum when in distributed mode
The check should always setup the execute[hbase-hdfs-rootdir] resource when the URI begins with hdfs:// and set it up when using just the path if hbase.cluster.distributed is set
Don't use deprecated property name
Rubocop can be a PITA, but I love it.
Remove redundant check for hbase_site key, since the above check would be fatal without it
