----------------------------------
Summary: [k8s] Spark client dependency support ignores non-local
paths
Key: SPARK-32775
URL: https://issues.apache.org/jira/browse/SPARK-32775
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 3.0.0
Reporter: Xuzhou Yin
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://upload/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.
