Your remote cluster reports the location of -ROOT- as on localhost on port 41181:
11/08/30 19:27:47 DEBUG client.HConnectionManager$HConnectionImplementation: Lookedup root region location, connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e<connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@10d593e>; hsa=localhost:41181 (hsa is the name of the class in HBase, HServerAddress) Is that "cluster" really just a standalone instance or something like that? That's usually what happens.
