Configuration

Pig uses the "hdfs" configuration. It also declare 2 optional properties:

• hdp.force_check (string) Force the execution of the check action on each run, otherwise it will run only on the first install. The property is shared by multiple modules and default to false.
• pig.user (object|string) The Unix Pig login name or a user object (see Nikita User documentation).
• hdp.pig.conf_dir (string) The Pig configuration directory, dont overwrite, default to "/etc/pig/conf".

Example:

{
  "ryba": {
    "pig": {
      "config": {
        "pig.cachedbag.memusage": "0.1",
        "pig.skewedjoin.reduce.memusage", "0.3"
      }
    },
    force_check: true
  }
}

module.exports = (service) ->
  options = service.options

  options.group ?= {}
  options.group = name: options.group if typeof options.group is 'string'
  options.group.name ?= 'pig'
  options.group.system ?= true
  # User
  options.user ?= {}
  options.user = name: options.user if typeof options.user is 'string'

  options.user.system ?= true
  options.user.gid ?= 'pig'
  options.user.comment ?= 'Pig User'
  options.user.home ?= '/var/lib/pig'

Test

  options.test = merge {}, service.deps.test_user.options, options.test
