----------------------------------
Summary: yarn-cluster mode offers a degraded performance from
yarn-client [Spark Branch]
Key: HIVE-10671
URL: https://issues.apache.org/jira/browse/HIVE-10671
Project: Hive
Issue Type: Bug
Components: Spark
Reporter: Xuefu Zhang
With Hive on Spark, users noticed that in certain cases
spark.master=yarn-client offers 2x or 3x better performance than if
spark.master=yarn-cluster. However, yarn-cluster is what we recommend and
support. Thus, we should investigate and fix the problem. One of the such
queries is TPC-H 22.
