Summary: Pretty print MutatedConfigurationException
Key: FLINK-30155
URL: https://issues.apache.org/jira/browse/FLINK-30155
Project: Flink
Issue Type: New Feature
Components: API / DataStream
Affects Versions: 1.17.0
Reporter: Piotr Nowojski
Assignee: Piotr Nowojski
Fix For: 1.17.0
Currently MutatedConfigurationException is printed as:
{noformat}
org.apache.flink.client.program.MutatedConfigurationException:
Configuration execution.sorted-inputs.enabled:true not allowed.
Configuration execution.runtime-mode was changed from STREAMING to BATCH.
Configuration execution.checkpointing.interval:500 ms not allowed in the
configuration object CheckpointConfig.
Configuration execution.checkpointing.mode:EXACTLY_ONCE not allowed in the
configuration object CheckpointConfig.
Configuration pipeline.max-parallelism:1024 not allowed in the
configuration object ExecutionConfig.
Configuration parallelism.default:25 not allowed in the configuration
object ExecutionConfig.

{noformat}
Which is slightly confusing. First not allowed configuration is listed in the
same line as the exception name, which (especially if wrapped) can make it more
difficult than necessary for user to understand that this is a list of
violations. I'm proposing to change it to:
{noformat}
org.apache.flink.client.program.MutatedConfigurationException: Not allowed
configuration change(s) were detected:
- Configuration execution.sorted-inputs.enabled:true not allowed.
- Configuration execution.runtime-mode was changed from STREAMING to BATCH.
- Configuration execution.checkpointing.interval:500 ms not allowed in the

To make it more clear.
