Szehon Ho commented on HIVE-8795:
---------------------------------
Hi Xuefu, I thought last time we could not get it work (after Rui and my
attempts) as some spark code was looking for a spark script in a predefined
path. Did something change in the meantime?
> Switch precommit test from local to local-cluster [Spark Branch]

> Key: HIVE-8795

> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Xuefu Zhang
> Assignee: Szehon Ho
>
> 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.
