> Key: FLINK-18641
> URL: https://issues.apache.org/jira/browse/FLINK-18641
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.11.0
> Reporter: Brian Zhou
> Assignee: Jiangjie Qin
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.12.0, 1.11.2

> https://github.com/pravega/flink-connectors is a Pravega connector for Flink.
> The ReaderCheckpointHook[1] class uses the Flink `MasterTriggerRestoreHook`
> interface to trigger the Pravega checkpoint during Flink checkpoints to make
> sure the data recovery. The checkpoint recovery tests are running fine in
> Flink 1.10, but it has below issues in Flink 1.11 causing the tests time out.
> Suspect it is related to the checkpoint coordinator thread model changes in
> Flink 1.11
> Error stacktrace:
