## Description The Spark SQL test \`ParquetRowIndexSuite: invalid row index column type - vectorized reader\` expects a \`SparkException\` with condition \`FAILED_READ_FILE\` when the row index temporary column is declared with the wrong type (e.g., \`StringType\` instead of \`LongType\`). Spark's vectorized reader wraps the \`RuntimeException\` from \`findRowIndexColumnIndexInSchema\` in a \`SparkException\` via \`QueryExecutionErrors.cannotReadFilesError()\`. Comet's \`NativeBatchReader\` lets the \`RuntimeException\` propagate unwrapped. ## Steps to reproduce Run the Spark SQL test suite \`ParquetRowIndexSuite\` with Comet enabled against Spark 4.0.1. ## Expected behavior \`SparkException\` with condition starting with \`FAILED_READ_FILE\` should be thrown, matching Spark's native behavior. ## Actual behavior \`RuntimeException\` is thrown directly. -- This is an automated message from the Apache Git Service.
