-------------------------------------
Summary: Flink Docker image creates checkpoints as root user and
hits permission denied afterwards
Key: FLINK-19111
URL: https://issues.apache.org/jira/browse/FLINK-19111
Project: Flink
Issue Type: Bug
Components: flink-docker
Affects Versions: 1.10.1, 1.10.0
Reporter: Tobias Kaymak
After upgrading my cluster using the official Docker image for Flink from 1.9
to 1.10.1 I noticed that all checkpoints failed for my existing pipelines.
Checkpoints are saved in a local (NFS backed) directory, so full UNIX
permissions apply.
I went onto the jobmanager pod and saw that it created the checkpoint folder
with root:root as the owner. Even after fixing this or giving it super relaxed
permissions (chmod 777) I couldn't make it work.
I checked the changes in the Flink Docker repository on GitHub, but couldn't
spot any {{gosu }}or similar related changes. I tried 1.10.2 too, but the issue
remained.
The web interface just gives me
*Failure Message:* The job has failed.
The logs show that there is in fact a permission problem:
