Xuefu Zhang commented on HIVE-7436:
-----------------------------------
[~chengxiang li] Thanks for working on this. With your proposal, I'm wondering
if user can run query on spark when spark-defaults.conf is missing from user's
environment. Would default configuration allow user to run spark, such as in
local mode?
Second question: would user be able to set or change the spark configuration
via hive's set command? I guess not, but I'd like to hear your thought.

> load Spark configuration into Hive driver, there are 3 ways to setup spark
> configurations:
> # Configure properties in spark configuration file(spark-defaults.conf).
> # Java property.
> # System environment.
> Spark support configuration through system environment just for compatible
> with previous scripts, we won't support in Hive on Spark. Hive on Spark load
> defaults from java properties, then load properties from configuration file,
> and override existed properties.
> configuration steps:
> # Create spark-defaults.conf, and place it in the /etc/spark/conf
> configuration directory.
> please refer to [http://spark.apache.org/docs/latest/configuration.html]
> for configuration of spark-defaults.conf.
> # Create the $SPARK_CONF_DIR environment variable and set it to the location
> of spark-defaults.conf.
> export SPARK_CONF_DIR=/etc/spark/conf
> # Add $SAPRK_CONF_DIR to the $HADOOP_CLASSPATH environment variable.
> export HADOOP_CLASSPATH=$SPARK_CONF_DIR:$HADOOP_CLASSPATH
> NO PRECOMMIT TESTS. This is for spark-branch only.
