The above looks pretty basic.   It looks like you are not running hdfs
or at least its not running where hbase has been told to go look for
it.

Please do not post raw log into mail messages.  Please use a service
like pastebin.  Logs in mail messages with line wrapping are hard to
parse.

Configure your hosts file properly..proper dns resplution is really
important and a bit tricky..also check your fs.default.name and
hbase.rootdir properties..they both should coincide..and add following two
jars into your HBASE_HOME/lib dorectory :
1. hadoop-core from your HADOOP_HOME
2. commons-collection from your
     HADOOP_HOME/lib

Hi stack,
The namenode, jobtracker and secondary namenode are working and no problem with them.
The problem is when I run this command
$host -v -t A `hostname`Trying "namenode"Host namenode not found: 3(NXDOMAIN)
I don't know why, so I want to ask a question do I have to let hostname = namenode.example.com (in the canonical form) or can leave it "namenode".
Note that my hostname is namenode.
Thanks,

Try following some of Mohammed's advise.  Fix the above networking issue first.
