> Spark Livy - Add Support for All Missing Session Features
> ---------------------------------------------------------
>
> Key: NIFI-6175
> URL: https://issues.apache.org/jira/browse/NIFI-6175
> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 1.9.2
> Reporter: Peter Wicks
> Assignee: Peter Wicks
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The Livy Session Controller is missing many of the options available, and
> many of them I feel are critical for this service to be useful (queue? conf?
> num of executors?)
> * Would like to see all available options there, with a blanket "conf"
> option for users to provide custom configuration.
> * When the controller service shuts down, sessions are left running, with no
> option to shut them down. Add in functionality to shutdown open sessions.
> * If the controller service finds no Idle Livy Sessions, it will create a
> new session... until the queue runs out of resources :). Need to have a
> Min/Max/Should be elastic or strict option
> * When Livy starts up, it searches for existing sessions, but does not
> verify that those sessions belong to it.
> ** The Kerberos identity should be used to verify the identity on the
> session matches the identity on the controller service.
> ** Also, if a Proxy user has been specified, that should also be verified.
> If no proxy user was specified, then the Proxy user on the Livy session
> should match the Kerberos identity.
> * The initialization of the SSL Context is not implemented in a thread safe
> way. This leads to exceptions when multiple threads are running against the
> same Controller Service.
> ** SSL Context init should be made thread safe.
