This is encouraging.
¨Make sure HDFS is running first. Start and stop the Hadoop HDFS daemons by
running bin/start-hdfs.sh over in the HADOOP_HOME directory. You can ensure
it started properly by testing the *put* and *get* of files into the Hadoop
filesystem. HBase does not normally use the mapreduce daemons. These do not
need to be started.¨
