> Project: Apache Ozone

> Affects Versions: 2.0.0
> Reporter: Devesh Kumar Singh

> Priority: Major

> h2. *Specific Failure Scenarios When OMDbUpdatesHandler could still hold some
> references*
> h3. *Scenario 1: Exception During Batch Processing*
> try (OMDBUpdatesHandler omdbUpdatesHandler = new
> OMDBUpdatesHandler(omMetadataManager)) {
> for (byte[] data : dbUpdates.getData()) {
> try (ManagedWriteBatch writeBatch = new ManagedWriteBatch(data)) {
> writeBatch.iterate(omdbUpdatesHandler); // Handler stores
> references to RocksDB objects
>
> // EXCEPTION OCCURS HERE (e.g., RocksDBException during commit)
> rdbBatchOperation.commit(rocksDB, wOpts);
>
> } // writeBatch.close() called, but omdbUpdatesHandler still holds
> references!
> }
> } // omdbUpdatesHandler "close" called, but it's a no-op since no close()
> method exists
>
> *Result:* RocksDB handles, iterators, and memory remain allocated
> indefinitely.
> h3. *Scenario 2: Interrupted Thread*
> try (OMDBUpdatesHandler omdbUpdatesHandler = new
> OMDBUpdatesHandler(omMetadataManager)) {
> // Thread gets interrupted during long-running operation
> if (Thread.currentThread().isInterrupted()) {
> throw new InterruptedException("Thread interrupted during delta
> update.");
> }
> // omdbUpdatesHandler has already accessed tables and created internal
> resources
> // Interrupt causes immediate exit without proper cleanup
> }
