+## Spark-submit Application
+
+### Local (Spark Driver running on local machine)
+
+With `--deploy-mode client` (default), the Spark Driver runs locally and doesn't pick up [spark-4.0-standalone.conf](../compose.spark-4.0-standalone.yaml), so the `--conf spark.hadoop.*` options must be set explicitly.
+
+```shell
+spark-submit \
+    --master spark://localhost:7077 \
+    --packages "com.google.cloud.bigdataoss:gcs-connector:4.0.2" \
+    --conf spark.eventLog.enabled=true \
+    --conf spark.eventLog.dir=file://$(pwd)/../logs/ \
+    --conf spark.hadoop.fs.gs.impl=com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem \
+    --conf spark.hadoop.fs.AbstractFileSystem.gs.impl=com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS \
