The hbase.zookeeper.quorum parameter sets the ZooKeeper quorum servers to be the three listed machines on
which ZooKeeper is installed. Setting the hbase.cluster.distributed parameter to True tells HBase that it is
set up as a cluster. Finally, the HBase parameter hbase.rootdir tells HBase where to access HDFS, while the HBase
hbase.master parameter tells HBase which node is the master node.
With all the pieces in place, I can start the HBase servers. To do so, I use the following script as the Linux root user
on each of the HBase cluster nodes:
for x in `cd /etc/init.d ; ls hbase-*` ; do service $x start ; done
This example installation was intended as a guide for completing your own installation. If all has gone well, you
have installed the components that Hue depends on and you are ready to start using Hue.
Starting Hue
Once the Hue service is started, the Hue error logs can be checked for errors. Some possible errors are described
in the section that follows. Also, you can try to access the Hue interface described in the section “Running Hue.”
Any configuration or operational errors will quickly become apparent. If you encounter a problem, recheck your
configuration steps for a mistake.
You now start the Hue service as the Linux root user using the service command. The Hue service is called “hue”:
[root@hc1nn init.d]# service hue start
Starting hue: [ OK ]
Once the Hue service is running, you can find the Hue logs under the Linux file system directory /var/log/hue.
Look through the logs for any error messages; if you find any, then check the section on errors. If you don't find a
solution there, check the Hue website at gethue.com :
[hadoop@hc1nn ~]$ cd /var/log/hue
[hadoop@hc1nn hue]$ ls -lrt
