---------------------------------------------

[~cloud_fan]  Have anyone tested this in HDP Clusters, I'm getting the same 
issue  as [~doriwal] , its works well in my local machine, but when I run this 
HDP cluster, the folder doesn't have any partitions created at all, all I can 
see is a _SUCCESS file created in the path; and If set this to static the 
partition folders are getting created.

 

I'm running my code on spark 2.3.0 version and hip version 2.6.5

 

Appreciate your inputs

>
> When we overwrite a partitioned data source table, currently Spark will 
> truncate the entire table to write new data, or truncate a bunch of 
> partitions according to the given static partitions.
> For example, {{INSERT OVERWRITE tbl ...}} will truncate the entire table, 
> {{INSERT OVERWRITE tbl PARTITION (a=1, b)}} will truncate all the partitions 
> that starts with {{a=1}}.
> This behavior is kind of reasonable as we can know which partitions will be 
> overwritten before runtime. However, hive has a different behavior that it 
> only overwrites related partitions, e.g. {{INSERT OVERWRITE tbl SELECT 
> 1,2,3}} will only overwrite partition {{a=2, b=3}}, assuming {{tbl}} has only 
> one data column and is partitioned by {{a}} and {{b}}.
> It seems better if we can follow hive's behavior.
