Billie Rinaldi commented on YARN-6405:
--------------------------------------
Yes, that's exactly what we want. Classic Slider apps (HBase, Accumulo, Solr,
etc.) write their data to HDFS and don't care where their containers are
running. Also, a major part of the usefulness of unique names is that
containers will have well-known hostnames, meaning they can assume that a
hostname like solr1.solr-app.user.domain will exist.
For ZooKeeper, which is a new type of app that writes its data locally, it is
even more important to have fixed hostnames because they are used in the
zoo.cfg file. But for ZooKeeper it seems like it will be okay if we can
configure infinite auto-restart for its containers, since that mimics the old
"strict placement" behavior. Is being able to configure that through the API on
the todo list?

> YARN-4793 defined various ways that user can config services through the
> configuration section of the REST API. But, some semantics are not yet
> supported in the back-end server (AM). YARN-6255 has done some work, this
> jira is to complete this task - support configuring services through REST API
