wangzhun created SPARK-30365:
--------------------------------
Summary: 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
{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
