[GitHub] [beam] kennknowles opened a new issue, #19255: UnboundedSourceWrapper checkpoints before starting Readers
kennknowles opened a new issue, #19255:
URL: https://github.com/apache/beam/issues/19255
When start has not been called on the Readers of CountingSource, the checkpoint may contain a null value which lets the AvroCoder fail with a NullpointerException.
UnboundedSourceWrapper should not attempt to checkpoint before the readers have been started. See UnboundedSource:
> getCheckpointMark not be called before \{@link #start\} has been called.
Imported from Jira [BEAM-6315](https://issues.apache.org/jira/browse/BEAM-6315). Original Jira may contain additional context.
