It will, if the region server tells the client that the region moved or was split, it throws a NotServingRegionException which the client understands and then asks the .META. region for the new location. So in each retry it does 2 round trips. Please read http://wiki.apache.org/hadoop/Hbase/HbaseArchitecture#client
