Known issuesedit

  • If autoscaling is enabled for machine learning, the administrator of the cluster should increase the cluster setting xpack.ml.max_open_jobs to the maximum value of 512. This allows autoscaling to run reliably as it relies on assigning jobs only via memory. Having xpack.ml.max_open_jobs as a small number may cause autoscaling to behave unexpectedly.
