--------------------------------
Summary: Snapshot master hook state asynchronously
Key: FLINK-14344
URL: https://issues.apache.org/jira/browse/FLINK-14344
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Reporter: Biao Liu
Fix For: 1.10.0
Currently we snapshot the master hook state synchronously. As a part of
reworking threading model of {{CheckpointCoordinator}}, we have to make this
non-blocking to satisfy the requirement of running in main thread.
The behavior of snapshotting master hook state should be similar to task state
snapshotting. It should be launched after \{{PendingCheckpoint}} created. It
could complete or fail the {{PendingCheckpoint}} like task state snapshotting.
