The Clusters.yml File
---------------------------------------------------------------------------------------------------
The "clusters.yml" file is a file Hodor reads at startup that allows you to define multiple hadoop
clusters, and the url and resource bindings they require, so that your Hodor session can be easily
switched between multiple available Hadoop clusters. Hodor''s namespaces and commands use the url
and resource bindings from clusters.yml to select the destination for its various SSH and REST
calls. The clusters.yml file is expected in your hadoop project git repo at the path:

    "<repo_root>/config/clusters.yml"

The clusters.yml file will typically look something like the following:

    :production:
      :nameNode: hdfs://hadoop-prod.mycompany.com:8020
      :jobTracker: hadoop-prod.mycompany.com:8050
      :oozie_url: http://hadoop-prod.mycompany.com:11000/oozie

    :staging:
      :nameNode: hdfs://hadoop-stage.mycompany.com:8020
      :jobTracker: hadoop-stage.mycompany.com:8050
      :oozie_url: http://hadoop-stage.mycompany.com:11000/oozie

The section (staging or production) that Hodor uses (e.g. the "target cluster") is configured using:

    $ export HADOOP_ENV=production

To display a list of all key/value pairs that are defined for the current target cluster:

    $ hodor master:config

To view more information about how the clusters.yml keys and values can be used to
parameterize your job properties, type:

    $ hodor oozie:topic compose_job_properties
