--------------------------------------
Summary: Restore from Checkpoint fails if checkpoint folders is
corrupt/partial
Key: FLINK-19359
URL: https://issues.apache.org/jira/browse/FLINK-19359
Project: Flink
Issue Type: Bug
Components: Runtime / Checkpointing
Affects Versions: 1.8.0
Reporter: Arpith Prakash
Attachments: Checkpoints.png
I'm using Flink 1.8.0 version and have enabled externalized checkpoint to hdfs
location, we have seen few scenarios where checkpoint folders will have
checkpoint files but only missing "*_metadata*" file. If we attempt to restore
application from this path, application fails with exception "Could not find
*_metadata* file. There is similar discussion in Flink user mailing list with
subject "Zookeeper connection loss causing checkpoint corruption" around it.
I've attached sample snapshot on how folder structure looks as well.
