-------------------------------------------------------------
What is the difference between this Jira and this one:
https://issues.apache.org/jira/browse/SPARK-20236
I tested this out with spark 2.2 this only works for external tables not
managed tables in hive? Any reason why is that?
With 2.3 we can enable/disable this behaviour via this property:
_spark.sql.sources.partitionOverwriteMode_ whereas previously it was default?
*Update:* I got it.
[SPARK-20236|https://issues.apache.org/jira/browse/SPARK-20236] provides a
feature flag to override this behaviour via the above mentioned property
whereas this Jira fixes the insert overwrite behaviour overall.

> Should fix INSERT OVERWRITE TABLE of Datasource tables with dynamic partitions
> ------------------------------------------------------------------------------

> Key: SPARK-18185
> URL: https://issues.apache.org/jira/browse/SPARK-18185
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Eric Liang
> Assignee: Eric Liang
> Priority: Major
> Fix For: 2.1.0
>
>
> As of current 2.1, INSERT OVERWRITE with dynamic partitions against a
> Datasource table will overwrite the entire table instead of only the updated
> partitions as in Hive. It also doesn't respect custom partition locations.
> We should delete only the proper partitions, scan the metastore for affected
> partitions with custom locations, and ensure that deletes/writes go to the
> right locations for those as well.
