Xuefu Zhang commented on HIVE-15302:
------------------------------------
I think there are two dependency on Spark from Hive
1. Spark runtime classes which used to be in spark-assembly.jar
2. spark-submit.sh script that is used to submit spark application for a hive
session.
For #1, I think spark.yarn.jars or spark.yarn.archive will do.
For #2, I think we still need SPARK_HOME unless we clone a simplified spark
installation in Hive directory structure, which is not ideal.
Thus, SPARK_HOME seems still required. If so, Hive can automatically figure out
spark.yarn.jars or spark.yarn.archive if it's not already set, from SPARK_HOME.
To speed file distribution, an admin can point any of this properties to an
HDFS location, which requires admin manually upload files to HDFS beforehand.
As to spark.yarn.archive, I think one needs to zip all the jars, not the folder
that contains the jar. However, I didn't try and verify this.

> This requirement becomes more and more unacceptable as SparkSQL becomes
