-------------------------------
Summary: Hive query should fail when it fails to initialize a
session in SetSparkReducerParallelism [Spark Branch]
Key: HIVE-10476
URL: https://issues.apache.org/jira/browse/HIVE-10476
Project: Hive
Issue Type: Improvement
Components: Spark
Affects Versions: spark-branch
Reporter: Chao Sun
Assignee: Chao Sun
Priority: Minor
Currently, for a Hive query HoS need to get a session
a session twice, once in SparkSetReducerParallelism, and another when
submitting the actual job.
The issue is that sometimes there's problem when launching a Yarn application
(e.g., don't have permission), then user will have to wait for two timeouts,
because both session initializations will fail. This turned out to happen
frequently.
This JIRA proposes to fail the query in SparkSetReducerParallelism, when it
cannot initialize the session.
