[jira] [Created] (FLINK-10615) Cancel with savepoint can fail the
job
Gary Yao created FLINK-10615:
--------------------------------
Summary: Cancel with savepoint can fail the job
Key: FLINK-10615
URL: https://issues.apache.org/jira/browse/FLINK-10615
Project: Flink
Issue Type: Bug
Components: Distributed Coordination, State Backends, Checkpointing
Affects Versions: 1.6.1, 1.5.4, 1.7.0
Environment: *Rev:* e96cdf12d6ff42079b39f5ef8966258e60083b48
Reporter: Gary Yao
Fix For: 1.8.0
*Description*
Cancelling a job with a savepoint can lead to a job failure, if {{failOnCheckpointingErrors}} is set to {{true}} in the checkpoint config.
*Analysis*
# The checkpoint scheduler gets stopped before taking the savepoint to ensure that no additional checkpoints are taken afterwards.
# All pending checkpoints are aborted, which leads to disposal of all the data at the checkpoint storage location.
# Job fails because the pending checkpoint cannot be finalized (see Stacktrace).
*Stacktrace*
