-----------------------------------
Summary: Fix BlockDataStreamOutput.hsync() exception handling
Key: HDDS-15225
URL: https://issues.apache.org/jira/browse/HDDS-15225
Project: Apache Ozone
Issue Type: Test
Components: Ozone Client
Reporter: István Fajth
Assignee: István Fajth
BlockDataStreamOutput.hsync() has an empty catch block that discards all
exceptions from handleFlush(). This means a failed putBlock or watchForCommit
during hsync is silently ignored, and the caller believes the sync succeeded.
KeyDataStreamOutput then proceeds to call OM hsyncKey() for data that was never
acknowledged by datanodes.
The Ratis path (RatisBlockOutputStream.hsync()) correctly propagates
exceptions. The fix aligns the DataStream hsync with the Ratis behavior:
propagate IOException directly, wrap checked exceptions in IOException.
Verification: unit tests skipped in HDDS-15170 turn green.
