Stephan Ewen commented on FLINK-4644:
-------------------------------------
It was initially used by the web frontend, IIRC.
+1 for deprecating it.
> Deprecate "flink.base.dir.path" from ConfigConstants

> Key: FLINK-4644

> Project: Flink
> Issue Type: Wish
> Affects Versions: 1.2.0
> Reporter: Maximilian Michels

> 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.
