Chao Sun created SPARK-33212: -------------------------------- Summary: Move to shaded clients for Hadoop 3.x profile Key: SPARK-33212 URL: https://issues.apache.org/jira/browse/SPARK-33212 Project: Spark Issue Type: Improvement Components: Spark Core, Spark Submit, SQL, YARN Affects Versions: 3.0.1 Reporter: Chao Sun
Hadoop 3.x+ offers shaded client jars: hadoop-client-api and hadoop-client-runtime, which shade 3rd party dependencies such as Guava, protobuf, jetty etc. This Jira switches Spark to use these jars instead of hadoop-common, hadoop-client etc. Benefits include: * It unblocks Spark from upgrading to Hadoop 3.2.2/3.3.0+. The newer versions of Hadoop have migrated to Guava 27.0+ and in order to resolve Guava conflicts, Spark depends on Hadoop to not leaking dependencies. * It makes Spark/Hadoop dependency cleaner. Currently Spark uses both client-side and server-side Hadoop APIs from modules such as hadoop-common, hadoop-yarn-server-common etc. Moving to hadoop-client-api allows use to only use public/client API from Hadoop side. * Provides a better isolation from Hadoop dependencies. In future Spark can better evolve without worrying about dependencies pulled from Hadoop side (which used to be a lot). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
