Yin Huai updated SPARK-30783:
-----------------------------
Description:
hive-service-rpc 2.3.6 and spark sql's thrift server module have duplicate
classes. Leaving hive-service-rpc 2.3.6 in the class path means that spark can
pick up classes defined in hive instead of its thrift server module, which can
cause hard to debug runtime errors due to class loading order and compilation
errors for applications depend on spark.
If you compare hive-service-rpc 2.3.6's jar
([https://search.maven.org/remotecontent?filepath=org/apache/hive/hive-service-rpc/2.3.6/hive-service-rpc-2.3.6.jar])
and spark thrift server's jar (e.g.
[https://repository.apache.org/content/groups/snapshots/org/apache/spark/spark-hive-thriftserver_2.12/3.0.0-SNAPSHOT/spark-hive-thriftserver_2.12-3.0.0-20200207.021914-364.jar),]
you will see that all of classes provided by hive-service-rpc-2.3.6.jar are
covered by spark thrift server's jar. I am attaching the list of jar contents
for your reference.
