the services that require it

                 Key: BIGTOP-479
                 URL: https://issues.apache.org/jira/browse/BIGTOP-479
             Project: Bigtop
          Issue Type: Bug
          Components: General
    Affects Versions: 0.4.0
            Reporter: Roman Shaposhnik
            Assignee: Roman Shaposhnik
             Fix For: 0.4.0


The following services require an explicit initialization of the persistent 
state in the local filesystem:
   # Hadoop NameNode (formatting a namenode via: hdfs namenode -format)
   # ZooKeeper (formatting a local storage area via: 
zookeeper-server-initialize)

and the following ones require an initialization of the RDBMS database (which 
can reside on a local filesystem
via Derby or be hosted on a remote server such as Postgress, MySQL, Oracle, 
etc.):
   # oozie DB (initialized via ooziedb.sh)
   # possible Hive metastore
   # possibly Sqoop metastore

In order to free the user from an explicit knowledge of what command to run 
under which account it is desirable
to have an init.d scripts for the above components support and extra command 
called 'init'.

Please let me know what do you all think.
