Xuefu Zhang commented on HIVE-8795:
-----------------------------------
Requiring a Spark installation can be as simple as downloading a tarball as
part of the build and untar it to a folder to which SPARK_HOME can be set. It's
possible, however, with Spark assembly + certain scripts, we may not even need
the tarball. However, I haven't tried this combination, but according to Spark
folks, this is possible.
> Switch precommit test from local to local-cluster [Spark Branch]

> It seems unlikely that Spark community will provide MRMiniCluster equivalent
> (SPARK-3691), and Spark local-cluster was the recommendation. Latest research
> shows that Spark local-cluster works with Hive. Therefore, for now, we use
> Spark local-cluster (instead of current local) for our precommit test.
> It's previous belived (HIVE-7382) that a Spark installation is required and
> SPARK_HOME env variable needs to set. Since Spark pulls in Spark's assembly
> jar, it's believed now we only need a few script from Spark installation
> instead.
