Gluten Support
Velox Backend
Gluten with velox backend supports Celeborn as remote shuffle service. Below introduction is used to enable this feature
First refer to Get Started With Velox to build Gluten with velox backend.
When compiling the Gluten Java module, it's required to enable rss profile, as follows:
mvn clean package -Pbackends-velox -Pspark-3.3 -Prss -DskipTests
Then add the Gluten and Spark Celeborn Client packages to your Spark application's classpath(usually add them into $SPARK_HOME/jars).
- Celeborn: celeborn-client-spark-3-shaded_2.12-0.3.0-incubating.jar
- Gluten: gluten-velox-bundle-spark3.x_2.12-xx-xx-SNAPSHOT.jar, gluten-thirdparty-lib-xx.jar
Currently to use Gluten following configurations are required in spark-defaults.conf
spark.shuffle.manager org.apache.spark.shuffle.gluten.celeborn.CelebornShuffleManager
# celeborn master
spark.celeborn.master.endpoints clb-master:9097
# we recommend set spark.celeborn.push.replicate.enabled to true to enable server-side data replication
# If you have only one worker, this setting must be false
spark.celeborn.client.push.replicate.enabled true
spark.celeborn.client.spark.shuffle.writer hash
# This is not necessary if your Spark external shuffle service is Spark 3.1 or newer
spark.shuffle.service.enabled false
spark.sql.adaptive.localShuffleReader.enabled false
# If you want to use dynamic resource allocation,
# please refer to this URL (https://github.com/apache/incubator-celeborn/tree/main/assets/spark-patch) to apply the patch into your own Spark.
spark.dynamicAllocation.enabled false
