---------------------------------------
Summary: Move zipping logic out of blobservice
Key: FLINK-9623
URL: https://issues.apache.org/jira/browse/FLINK-9623
Project: Flink
Issue Type: Improvement
Components: Job-Submission
Affects Versions: 1.6.0
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.6.0
Directories given to the blob-service (primarily a use-case for the distributed
cache) are currently silently zipped, and later unzipped by the {{FileCache}}.
This tightly coupled the zipping logic in the blob-service to the unzipping
logic of the {{FileCache}}. The blob-service neither unzipped the directory if
the blob was requested, nor did it provide any means of doing so manually, nor
did it inform the user as to whether the requested blob is a zip or not.
My conclusion in is that the blob-service should not support directories _for
now_, and that instead directories for the {{distributed cache}} should be
explicitly zipped beforehand, given that this is the only use-case we have at
the moment.
