Rui Li commented on HIVE-18533:
-------------------------------
Seems the new qtest has unstable output. Please look into it.
Some more comments:
# The new configuration takes values like {{SPARK_SUBMIT_CLIENT}} and
{{SPARK_LAUNCHER_CLIENT}}. How about just use "submit" and "launcher" instead,
which are user friendly and more like conventional Hive configs?
# {{hive.spark.client.type}} needs to be added to
{{HIVE_SPARK_RSC_CONF_LIST}}, so changing it will create a new session.
# More Spark jars need to be added to Hive in order to use the new client. I
found 3 extra jars: {{scala-reflect}}, {{spark-launcher}} and {{spark-yarn}}.
We can update the
[wiki|https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started#HiveonSpark:GettingStarted-ConfiguringHive]
once the patch is in.
