Subject [GitHub] flink pull request: [FLINK-2805] [blobmanager] Write JARs to file ...

    - It is very tightly coupled in in case of recovery. We won't loose this, but I agree
to introduce an interface to hide this (with a no-op implementation for standalone mode and
the filesystem implementation in case of recovery). I fully agree that it's not a good way
to do it, but this is blocking #1153. Is that OK?
    - There is no check for the provided path. It's the same behaviour as the configured checkpoint
directory `STATE_BACKEND_FS_DIR`. I think the check would have to be performed on the task
managers. A check for "file://" does not suffice, because this can also be a DFS. I would
open a issue for this and then fix it for the `STATE_BACKEND_FS_DIR` as well.
    - I'm still undecided about the shutdown hook. It was removed to exactly prevent SIGTERM
from removing all recovery data, but the actor postStop will be called after SIGTERM as well
and then it will remove it anyways. I think the only advantage (which doesn't justify it)
is for tests.
