ASF GitHub Bot commented on FLINK-5229: --------------------------------------- Github user tillrohrmann commented on the issue: https://github.com/apache/flink/pull/3179 I've addressed your comments @StefanRRichter. Note that I did not add the additional state object cleanup, because it was already done by cancelling the `OperatorSnapshotResults`. > Cleanup StreamTaskStates if a checkpoint operation of a subsequent operator > fails > ---------------------------------------------------------------------------------- > > Key: FLINK-5229 > URL: https://issues.apache.org/jira/browse/FLINK-5229 > Project: Flink > Issue Type: Bug > Components: State Backends, Checkpointing, TaskManager > Affects Versions: 1.2.0, 1.1.3 > Reporter: Till Rohrmann > Assignee: Till Rohrmann > Fix For: 1.2.0, 1.1.4 > > > Due to chaining, a {{StreamTask}} needs to checkpoint multiple operators. If > the first operators succeed in creating a checkpoint but a subsequent > operator in the chain fails, the {{StreamTask}} has to clean up the already > completed checkpoints. Otherwise we might end up with orphaned state data. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
