Comment 16 for bug 1272083

HPCC charm is re-submitted after 4th review with following update:

1) remove extra precise/hpcc directories in repository.

2) enforce checksum validation before installing HPCC package. If checksum not
   supplied message will be logged with juju-log (though log as INFO) and exit 1
   We will defer sha1sum implementation due to the time limit.

3) Add check status after starting HPCC. It is neccessory even start run
   successfully (return code 0) becasue some processes may exit unexpectedly.
   A variable "start-check-wait" in seconds is introduced in config.yaml to delay
   the checking.
   If error found messsage logged to tell user where to find the detail about
   the error: /var/log/HPCCSystems/<component>/

4) Update README. It adds a link to HPCC Hardware requirement. HPCC require
   4GB memory. With less memory some processes may not start successfully or
   even started may not function correctly.

Thanks
