Updates certain properties of an {anomaly-job}.

The following properties can be updated after the job is created:

`allow_lazy_open`::
(boolean)
include::{es-repo-dir}/ml/ml-shared.asciidoc[tag=allow-lazy-open]

--
NOTE: If the job is open when you make the update, you must stop the {dfeed},
close the job, then reopen the job and restart the {dfeed} for the changes to take effect.

(long or string)

+
--
NOTE: You can update the `analysis_limits` only while the job is closed. The 
`model_memory_limit` property value cannot be decreased below the current usage.
 
TIP: If the `memory_status` property in the
<<ml-get-snapshot-results,`model_size_stats` object>> has a value of 
`hard_limit`,mthis means that it was unable to process some data. You might want 
to re-run the job with an increased `model_memory_limit`.
