wangzhun updated SPARK-30365:
-----------------------------
Priority: Major (was: Minor)
> When deploy mode is a client, why doesn't it support remote "spark.files"
> download?
> -----------------------------------------------------------------------------------
>
> Key: SPARK-30365
> URL: https://issues.apache.org/jira/browse/SPARK-30365
> Project: Spark
> Issue Type: Question
> Components: Spark Submit
> Affects Versions: 2.3.2
> Environment: {code:java}
> ./bin/spark-submit \
> --master yarn \
> --deploy-mode client \
> ......{code}
> Reporter: wangzhun
> Priority: Major
>
> {code:java}
> // In client mode, download remote files.
> var localPrimaryResource: String = null
> var localJars: String = null
> var localPyFiles: String = null
> if (deployMode == CLIENT) {
> localPrimaryResource = Option(args.primaryResource).map {
> downloadFile(_, targetDir, sparkConf, hadoopConf, secMgr)
> }.orNull
> localJars = Option(args.jars).map {
> downloadFileList(_, targetDir, sparkConf, hadoopConf, secMgr)
> }.orNull
> localPyFiles = Option(args.pyFiles).map {
> downloadFileList(_, targetDir, sparkConf, hadoopConf, secMgr)
> }.orNull
> }
> {code}
> The above Spark2.3 SparkSubmit code does not download the corresponding file
> of "spark.files".
> I think it is possible to download remote files locally and add them to
> classPath.
> For example, can support --files configuration remote hive-site.xml
