### Backend VL (Velox) ### Bug description Based on my tests, some bugs have caused this issue: 1. Currently, `VeloxBackend::initUdf()` is called before `UDFResolver.loadAndGetFunctionDescriptions()`, so the `udflibPath` cannot be resolved on the driver. 2. When using `SparkFiles.get(f)` to retrieve a local file, it does not work on the driver in `yarn-client` or `yarn-cluster` mode. This is because the `--files/--archives` options set different Spark configuration keys, which are determined by the type of cluster manager and the deploy mode. If we use `--master=yarn`, then the Spark configuration keys `spark.yarn.dist.files`/`spark.yarn.dist.archives` will be set, and the file will be distributed to the working directory on all nodes(both driver and executors). Otherwise, `spark.files`/`spark.archives` will be set, and the files are added by `SparkContext.addFile`, which can be accessed by `SparkFiles.get()`. The Spark code that processes the --files and --archives arguments can be found at: https://github.com/apache/spark/blob/25ecde948bebf01d2cb1e160516238e1d949ffdb/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L653 ### Spark version Spark-3.2.x ### Spark configurations _No response_ ### System information _No response_ ### Relevant logs _No response_ -- This is an automated message from the Apache Git Service.
