echonesis opened a new pull request, #11940: URL: https://github.com/apache/ozone/pull/11940
## What changes were proposed in this pull request? After an EC reconstruction read or seek fails, a subsequent read on the same stream can return incomplete stripe buffers without reporting an error. A failed seek can also leave buffers containing data from the target stripe while the logical position remains unchanged. This pull request: - Invalidates stripe buffers when a stripe read throws an `IOException` or `RuntimeException`, preventing incomplete data from being returned. - Reuses the existing `unBuffered` flag to reposition the stripe reader before the next read, preserving the logical position after a failed seek. - Adds regression tests for exhausted replicas, failed seeks with both exception types, and reads that fail after partial progress across stripes. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-17001 ## How was this patch tested? ### Local Tests ```bash # HDDS client unit tests mvn -pl :hdds-client test \ -Dtest=TestECBlockInputStream,TestECBlockInputStreamProxy,TestECBlockReconstructedInputStream,TestECBlockReconstructedStripeInputStream \ -DskipShade -DskipRecon # Ozone client unit tests mvn -pl :ozone-client test \ -Dtest=TestOzoneECClient,TestKeyInputStreamEC \ -DskipShade -DskipRecon ``` GitHub Actions CI: https://github.com/echonesis/ozone/actions/runs/41596225383 Generated-by: Codex (GPT-6) -- This is an automated message from the Apache Git Service.
