>From http://hbase.apache.org/book/os.html:
HBase expects the loopback IP address to be 127.0.0.1. Ubuntu and some
other distributions, for example, will default to 127.0.1.1 and this
will cause problems for you.
It worths reading the whole section ;-).
You also don't need to set the master address: it will be read from
zookeeper. I.e. you can remove this line from your client code:
>> > config.set("hbase.master", "10.78.32.131:60010");
