### What changes were proposed in this pull request? - Bump orc.version in root and standalone-metastore pom.xml. - Add explicit org.jetbrains:annotations dependency (ORC 2.3 no longer pulls it transitively). - Fix ORC-related unit tests for ORC 2.3 stripe/memory-check behavior (TestFixAcidKeyIndex, TestOrcFileStripeMergeRecordReader, TestInputOutputFormat). - qtest golden files ### Why are the changes needed? https://issues.apache.org/jira/browse/HIVE-29585 Starting with ORC 2.3.0, LZ4 compression is implemented natively in ORC rather than via Aircompressor. This matters because Aircompressor’s LZ4 path does not support direct buffers which can affect performance in zero-copy I/O paths (e.g. LLAP). Aircompressor is still supported as an alternative but ORC’s built-in LZ4 is now the default. ### Does this PR introduce _any_ user-facing change? ORC 2.3.0 ships a native LZ4 codec. Hive previously relied on Aircompressor for LZ4, which lacks direct-buffer support and can limit efficiency in direct-buffer read/write scenarios. The upgrade moves to ORC’s native implementation by default. Aircompressor remains configurable for compatibility. ### How was this patch tested?
