[jira] [Updated] (FLINK-25765) Kubernetes: flink's configmap and flink's actual config are out of sync
[ https://issues.apache.org/jira/browse/FLINK-25765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Niklas Semmler updated FLINK-25765:
-----------------------------------
Description:
For kubernetes setups, Flink's configmap does not reflect the actual config.
Causes
# Config values are overridden by the environment variables in the docker image (see FLINK-25764)
# Flink reads the config on start-up, but does not subscribe to changes
# Changes to the config map do not lead to restarts of the flink cluster
Effects
# Users cannot expect to understand Flink's config from the configmap
# TaskManager/JobManager started at different times may start with different configs, if the user edits the configmap
Related to FLINK-21383.
