  When deploying clusters with the vanilla plugin, the Oozie[1]
  application must be configured to use a database for storing data
  related to the scheduling, running, and processing of Hadoop jobs.
  Oozie is the primary scheduler for jobs entering the Hadoop ecosystem
  through the vanilla plugin.

  Sahara configures the credentials for Oozie to access its database,
  this can be seen in sahara/plugins/vanilla/hadoop2/oozie_helper.py
  [2].  These credentials are hardcoded, and use a weak password.

  An intruder with access to the nodes of a cluster that is created by
  sahara with the vanilla plugin will have access to the database that
  backs the Oozie installation. With this access, the intruder could
  change the operational effects of Oozie to produce results other than
  expected, for example inserting new jobs or altering configurations
  associated with currently running jobs.

  As sahara has ultimate control over the deployment and configuration
  of Oozie on nodes deployed in its clusters, this hardcoded password
  should be changed in favor of a random password that will be generated
  uniquely for each deployed cluster. Oozie uses the values associated
  with the configurations defined in [2] to create the credentials, this
  means that the change should be a matter of simply changing the source
  valueof the password for the Oozie user.
