From e95999bcb6ca928393270d33319e7c0888b73a6e Mon Sep 17 00:00:00 2001 From: Chang chen Date: Fri, 27 Feb 2026 16:52:42 +0000 Subject: [PATCH 1/5] Translate Velox type conversion errors to SchemaColumnConvertNotSupportedException Add exception translation in Gluten's iterator chain so that Velox native reader type conversion errors are properly translated to Spark's expected SchemaColumnConvertNotSupportedException. Changes: - ClosableIterator.java: Extract translateException() virtual method (default returns GlutenException, preserving existing behavior) - ColumnarBatchOutIterator.java: Override translateException() to detect Velox type mapping errors ('not allowed for requested type' or 'Not a valid type for') and wrap them as SchemaColumnConvertNotSupportedException This enables Spark's ParquetTypeWideningSuite error-path tests to pass when using Gluten's Velox native reader.

Test suite: 81 pass, 0 fail, 38 ignored (from 74 failures) Changes: - VeloxTestSettings.scala (spark40+41): Enable suite with targeted excludes for DELTA_BYTE_ARRAY encoding limitation (2) and parquet-mr overflow (1) - GlutenParquetTypeWideningSuite.scala (spark40+41): Override test class to disable native writer (test read-path only) and override 35 tests that need expectError=true for both reader configs (Velox always uses native reader regardless of vectorized setting) - get-velox.sh: Point to Velox branch with type widening support Velox fixes (in baibaichen/velox feature/enable-parquet-type-widening-suite): 1. Revert OAP commit that over-relaxed convertType() type checks 2. Support INT->DOUBLE/REAL/DECIMAL widening + decimal precision check 3.
