------------------------------------
Summary: Close checkpoint streams upon cancellation
Key: FLINK-5215
URL: https://issues.apache.org/jira/browse/FLINK-5215
Project: Flink
Issue Type: Bug
Components: TaskManager
Affects Versions: 1.1.3
Reporter: Till Rohrmann
Fix For: 1.1.4
Closing checkpoint streams upon cancellation of a {{Task}} could help to
interrupt the main thread being stuck in the {{snapshotState}} method of
stateful operator. Otherwise, ff the snapshotState method takes too long to
complete, the watch dog will kill the whole {{TaskManager}} terminating all
other running tasks as well.
