   `xpack.ml.node_concurrent_job_allocations`::
   (<<cluster-update-settings,Dynamic>>) The maximum number of jobs that can
   concurrently be in the `opening` state on each node. Typically, jobs spend a
   small amount of time in this state before they move to `open` state. Jobs that
   must restore large models when they are opening spend more time in the `opening`
  -state. Defaults to `2`.

positive.code: is done by processes that run separately to the {es} JVM. When such processes
  are started they must connect to the {es} JVM. If such a process does not
  connect within the time period specified by this setting then the process is
  assumed to have failed. Defaults to `10s`. The minimum value for this setting is
  `5s`.
  
  xpack.ml.use_auto_machine_memory_percent::
  (<<cluster-update-settings,Dynamic>>) If this setting is `true`, the
  
negative.code: processes is calculated automatically and takes into account the total node size
  and the size of the JVM on the node. The default value is `false`. If this
  setting differs between nodes, the value on the current master node is heeded.
  When the {operator-feature} is enabled, this setting can be updated only by
  operator users.
