----------------------------------
Summary: Remove extra storage location for externalized checkpoint
metadata
Key: FLINK-4814
URL: https://issues.apache.org/jira/browse/FLINK-4814
Project: Flink
Issue Type: Improvement
Reporter: Ufuk Celebi
Follow up for FLINK-4512.
Store checkpoint meta data in checkpoint directory. That makes it simpler for
users to track and clean up checkpoints manually, if they want to retain
externalized checkpoints across cancellations and terminal failures.
Every state backend needs to be able to provide a storage location for the
checkpoint metadata. The memory state backend would hence not work with
externalized checkpoints, unless one sets explicitly a parameter
`setExternalizedCheckpointsLocation(uri)`.
