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

             Summary: Deprecate "flink.base.dir.path" from ConfigConstants
                 Key: FLINK-4644
                 URL: https://issues.apache.org/jira/browse/FLINK-4644
             Project: Flink
          Issue Type: Wish
    Affects Versions: 1.2.0
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
            Priority: Minor
             Fix For: 1.2.0


Flink's configuration entry "flink.base.dir.path" is not documented anywhere but present in {{ConfigConstants}}. It is set in the JobManager but it is not accessed anywhere in the code.

I propose to deprecate the entry from ConfigConstants:

public static final String FLINK_BASE_DIR_PATH_KEY = "flink.base.dir.path";

I think this entry can only possibly be abused by users to write into the Flink base dir or rely on some structure of the directory (which is different for standalone, yarn/mesos). The only way i can see such a variable being useful if it is present in the form of an environment variable to make it available to other systems.
