Chesnay Schepler commented on FLINK-8350:
-----------------------------------------
I'm not so sure about making {{taskmanager.tmp.dirs}} a deprecated key that is
shared across all components. That would mean that an outdated configurations
may suddenly affect the jobmanager.
> replace "taskmanager.tmp.dirs" with "env.io.tmp.dirs" for all components

> Key: FLINK-8350
> URL: https://issues.apache.org/jira/browse/FLINK-8350
> Project: Flink
> Issue Type: Improvement
> Components: Cluster Management, Configuration
> Affects Versions: 1.4.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
>
> Currently, there is only a {{taskmanager.tmp.dirs}} configuration parameter
> which (if unset) is set to YARN/Mesos' application environment paths (the
> latter not quite yet). With FLINK-8279, we also used this as a fall-back for
> the BLOB caches and would like to use it for the BLOB server as well. This,
> however, does not reside on the TaskManager and it only makes sense to have a
> single temporary directory configuration parameter (if desired, this could be
> extended).
> I propose to change this to a more generic {{env.io.tmp.dirs}} used by all
> components, i.e. JobManager, JobMaster, Dispatcher, and all the
> TaskManager-related instances for both YARN and Mesos.
>
> TODO: set this value to the appropriate folders for the JobManager code
> paths
> during cluster deployment (this exists for the TaskManager only for now)
