----------------------------------

             Summary: 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)
