I have met this problem, When I run the code HBaseAdmin admin = new HbaseAdmin(conf); the console print these messeages as below: 08/01/17 18:46:46 INFO ipc.Client: Retrying connect to server: /0.0.0.0:60000. Already tried 1 time(s). 08/01/17 18:46:47 INFO ipc.Client: Retrying connect to server: /0.0.0.0:60000.
