[jira] [Updated] (SPARK-32775) [k8s] Spark client dependency
support ignores non-local paths
[ https://issues.apache.org/jira/browse/SPARK-32775?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xuzhou Yin updated SPARK-32775:
-------------------------------
Description:
According to the logic of this line: [https://github.com/apache/spark/blob/master/resource-managers/kubernetes/core/src/main/scala/org/apache/spark/deploy/k8s/features/BasicDriverFeatureStep.scala#L161,] Spark filters out all paths which are not local (ie. no scheme or [file://|file:///] scheme). It may cause non-local dependencies not loaded by Driver.
For example, when starting a Spark job with spark.jars=*local*:///local/path/1.jar,*s3*://s3/path/2.jar,*file*:///local/path/3.jar, it seems like this logic will upload *file*:///local/path/3.jar to s3, and reset spark.jars to only s3://transformed/path/3.jar, while completely ignoring local:///local/path/1.jar and s3:///s3/path/2.jar.
We need to fix this logic such that Spark upload local files to S3, and transform the paths while keeping all other paths as they are.
