To run HBase you must have installed Hadoop underneath. The Hadoop top level
command line script 'bin/hadoop' is available in your Hadoop installation. Just
put the Hadoop bin/ dir on the path along with the HBase bin/ dir.
You can also run some Hadoop applications using the HBase command script, but
that is missing the shortcuts, e.g. instead of
hadoop fs -copyFromLocal ...
it is
hbase org.apache.hadoop.fs.FsShell -copyFromLocal ...
This will work for DFS but for other filesystems which need supporting jars in
lib/, your mileage will vary. Just put the Hadoop bin/ dir on the path along
with the HBase bin/ dir and use the appropriate one for the circumstances.

Subject: Re: Can I use hadoop inside hbase?
Thanks for the quick clarification Jeff.
In hbase distribution, I am unable to find hadoop command to load files
into DFS. How do I add hadoop commands to hbase distribution?
