HBase-client install fails when HDFS has not been installed

the problem is that the installing of hbase-client is before hdfs-client, and the hdfs-client installed failed because the hadoop-conf-dir didn't exist.
so there are two ways to solve this problem.
the first method is that create the hadoop-conf-dir in hbase.py
the second method is that setting the orders in role_command_order.json.
I think that we can take the first method.

Maybe
there is no necessary to deal with hdfs-site about hadoop_conf_dir in hbase.py.
