Kip Kohn resolved GOBBLIN-1972.
-------------------------------
Resolution: Fixed
> Fix Iceberg-Distcp, which now erroneously shows the job finishing as
> "SUCCESSFUL", despite the commit step failing with an exception.

>
> Key: GOBBLIN-1972
> URL: https://issues.apache.org/jira/browse/GOBBLIN-1972
> Project: Apache Gobblin
> Issue Type: Bug
> Components: gobblin-core
> Reporter: Kip Kohn
> Assignee: Abhishek Tiwari
> Priority: Major
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> Find and fix what appears to be a regression in `CopyDataPublisher` or
> `SafeDatasetCommit`...
> Here, the same Iceberg-Distcp `CommitStep` fails
> (`org.apache.gobblin.data.management.copy.iceberg.IcebergRegisterStep`), but
> with apache gobblin build `0.18.0-dev-493` it correctly shows "FAILED" yet
> with `0.18.0-dev-515` it claims "SUCCEEDED".
> BOTH display the same error:
> {code:java}
> ERROR [CopyDataPublisher] [Azkaban] Failed to publish tracking_db.MyEvent
> [then the exception stacktrace for the commit step, followed by...]
> ERROR [SafeDatasetCommit] [Azkaban] Failed to commit dataset
> - java.io.IOException: Not all datasets published successfully
> - at
> org.apache.gobblin.data.management.copy.publisher.CopyDataPublisher.publishData(CopyDataPublisher.java:160)
