-------------------------------
Summary: StreamTask waits for all the asynchronous step of pending
checkpoint to finish
Key: FLINK-21087
URL: https://issues.apache.org/jira/browse/FLINK-21087
Project: Flink
Issue Type: Sub-task
Components: Runtime / Checkpointing
Reporter: Yun Gao
Currently the snapshot process contains the synchronous and asynchronous steps.
When a StreamTask going to finish, there might be some pending checkpoints that
are still running their asynchronous step. Currently StreamTask would abort
these pending checkpoints since checkpoints after tasks finished are not
support, and it need to be changed to StreamTask wait for these pending
checkpoint to finish.
