Unsupported partition commit predicate

Error message

Unsupported partition commit predicate: {trigger}

What it means

Thrown by PartitionCommitPredicate.create when the configured 'sink.partition-commit.trigger' type maps to neither the partition-time nor processing-time predicate — the switch over PartitionCommitTriggerType falls through to an unsupported branch. The '{trigger}' literal is an unsubstituted placeholder for the trigger enum value read from configuration.

Solutions

  1. Address the cause reported by the error message: Unsupported partition commit predicate: the reported value
  2. Verify the inputs, configuration values, and classpath/dependency setup related to this operation, then retry.

Example fix

Correct the condition described ("Unsupported partition commit predicate: the reported value") and rerun the job or command.
Defensive patterns

Strategy: validation

When it happens

Trigger: Triggered at runtime when the operation fails because: Unsupported partition commit predicate: the reported value.

Common situations: Commonly caused by misconfiguration, missing dependencies or files, unsupported types or operations, or invalid user input leading to: Unsupported partition commit predicate: the reported value.
