Subject [jira] [Commented] (HIVE-11133) Support hive.explain.user for Spark [Spark Branch]
Date Wed, 19 Apr 2017 14:54:41 GMT


Sahil Takiar commented on HIVE-11133:

[~xuefuz] could you take a look? This patch basically adds support for User-Level Explain
plans to HoS. Previously, it only worked for Tez. User-Level Explain plans were added in HIVE-9780
and the documentation can be found [here|].
My comment [here|#comment-15966675] has an explanation of the changes. And I have made a few
more changes since then:

* Added a new config called {{hive.spark.explain.user}} that is an equivalent of {{hive.explain.user}}
but is Spark specific. {{hive.explain.user}} is true by default, {{hive.spark.explain.user}}
is false by default
* I copied {{explainuser_1.q}} to {{spark_explainuser_1.q}} and generated a {{spark_explainuser_1.q.out}}
file - I confirmed that the new explain plans look correct
