baibaichen opened a new issue, #8580: URL: https://github.com/apache/incubator-gluten/issues/8580
### Problem description Both ch and velox support `InputFileName`, `InputFileBlockStart` and `InputFileBlockLength`, but we still get the following warning: ```shell WARN org.apache.gluten.execution.ProjectExecTransformer: Validation failed with exception for plan: ProjectExecTransformer, due to: Not supported to map spark function name to substrait function name: input_file_name(), class name: InputFileName. ``` In addition, spark supports `InputXXX` through `ThreadLocal`, while Gluten supports them through push down. IIUC, the following codes colud be removed, after this [pr](https://github.com/apache/incubator-gluten/pull/7188) and https://github.com/apache/incubator-gluten/pull/7124. ``` GlutenWholeStageColumnarRDD::compute() // To support input_file_name(). According to semantic we should return // the exact file name a row belongs to. However in columnar engine it's // not easy to accomplish this. so we return a list of file(part) names split match { case FirstZippedPartitionsPartition(_, g: GlutenPartition, _) => InputFileBlockHolderProxy.set(g.files.mkString(",")) case _ => InputFileBlockHolderProxy.unset() } ``` ### System information no ### CMake log ```bash ``` -- This is an automated message from the Apache Git Service.
