[jira] [Updated] (FLINK-19778) Failed job reinitiated with wrong
checkpoint after a ZK reconnection
[ https://issues.apache.org/jira/browse/FLINK-19778?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Lin updated FLINK-19778:
-----------------------------
Description:
We have a job of Flink 1.11.0 running on YARN that reached FAILED state because its jobmanager lost leadership during a ZK full GC. But after the ZK connection was recovered, somehow the job was reinitiated again with no checkpoints found in ZK, and hence used an earlier savepoint to restore the job, which rewound the job unexpectedly.
For details please see the jobmanager logs in the attachment.
