I just wrote a simplest java class which read data form remote hbase,
the code as below;
HBaseConfiguration conf=new HBaseConfiguration();
conf.set("hbase.master", "remote computer ip : 60000");
HTable hTable=new HTable(conf, new Text(table name));
finally system print as follow:
08/05/26 10:03:41 INFO ipc.Client: Retrying connect to server:
/127.0.1.1:60020. Already tried 1 time(s).
08/05/26 10:04:03 INFO ipc.Client: Retrying connect to server:
/127.0.1.1:60020. Already tried 2 time(s).
08/05/26 10:04:25 INFO ipc.Client: Retrying connect to server:
