skonto opened a new pull request #23546: [SPARK-23153][K8s] Support client dependencies for HCFS
URL: https://github.com/apache/spark/pull/23546
 
 
   ## What changes were proposed in this pull request?
   - solves the issue with --packages. Keep in mind of some [issues](https://issues.apache.org/jira/browse/SPARK-22657) of the past.
   - use a custom scheme to denote local deps. Uploads the deps to the HCFS. 
   Then the driver serves the deps via the Spark file server.
   TODO: add integration tests using [minio](https://github.com/minio/cookbook/blob/master/docs/apache-spark-with-minio.md).
   
   ## How was this patch tested?
   
   - Run integration test suite.
   - Run an example using S3: 
   
   ```
    ./bin/spark-submit \
    --verbose \
    --master k8s://https://..... \
    --packages com.amazonaws:aws-java-sdk:1.7.4,org.apache.hadoop:hadoop-aws:2.7.6 \
    --deploy-mode cluster \
    --name spark-pi \
    --class org.apache.spark.examples.SparkPi \
    --conf spark.executor.memory=1G \
    --conf spark.kubernetes.namespace=spark \
    --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark-sa \
    --conf spark.driver.memory=1G \
    --conf spark.executor.instances=2 \
    --conf spark.sql.streaming.metricsEnabled=true \
    --conf "spark.driver.extraJavaOptions=-Divy.cache.dir=/tmp -Divy.home=/tmp" \
    --conf spark.kubernetes.container.image.pullPolicy=Always \
    --conf spark.kubernetes.container.image=skonto/spark:k8s-3.0.0 \
    --conf spark.kubernetes.file.upload.path=s3a://fdp-stavros-test \
    --conf spark.hadoop.fs.s3a.access.key=... \
    --conf spark.hadoop.fs.s3a.impl=org.apache.hadoop.fs.s3a.S3AFileSystem \
    --conf spark.hadoop.fs.s3a.fast.upload=true \
    --conf spark.kubernetes.executor.deleteOnTermination=false \
    --conf spark.hadoop.fs.s3a.secret.key=... \
    --conf spark.files=client:///home/ubuntu/resolv.conf \
     client:///my.jar
