[SPARK-23542] The exists action shoule be further optimized in logical plan

## What changes were proposed in this pull request?

(Please fill in changes proposed in this fix)
The optimized logical plan of query `select * from tt1 where exists (select 
*  from tt2  where tt1.i = tt2.i)` is

> == Optimized Logical Plan ==
Join LeftSemi, (i#14 = i#16)
  :- HiveTableRelation `default`.`tt1`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#14, s#15]
 +- Project [i#16]
  +- HiveTableRelation `default`.`tt2`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#16, s#17]

 The `exists` action will be rewritten as semi jion. But i the query of 
`select * from tt1 left semi join tt2 on tt2.i = tt1.i`, the optimized logical 
plan is :

> == Optimized Logical Plan ==
Join LeftSemi, (i#22 = i#20)
:- `Filter isnotnull`(i#20)
: +- HiveTableRelation `default`.`tt1`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#20, s#21]
+- Project [i#22]
+- HiveTableRelation `default`.`tt2`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#22, s#23]

 So i think the  optimized logical plan of 'select * from tt1 where exists 
(select *  from tt2  where tt1.i = tt2.i);` should be further optimization.
## How was this patch tested?

(Please explain how this patch was tested. E.g. unit tests, integration 
tests, manual tests)
(If this patch involves UI changes, please attach a screenshot; otherwise, 
remove this)

With this patch, the  optimized logical plan of 'select * from tt1 where 
exists (select *  from tt2  where tt1.i = tt2.i);`  is:

> == Optimized Logical Plan ==
Join LeftSemi, (i#14 = i#16)
:- Filter isnotnull(i#14)
  : +- HiveTableRelation `default`.`tt1`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#14, s#15]
+- Project [i#16]
 :- Filter isnotnull(i#16)
  +- HiveTableRelation `default`.`tt2`, 
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [i#16, s#17]

Is this check necessary? I think check `originalPlan.output !=

2018-03-20 Thread mn-mikke
Github user mn-mikke commented on the issue:

https://github.com/apache/spark/pull/20858
  
@maropu What other libraries do you mean? I'm not aware of any library 
providing this functionality on top Spark SQL.

When using Spark SQL as an ETL tool for structured and nested data, people 
are forced to use UDFs for transforming arrays since current api for array 
columns is lacking. This approach brings several drawbacks:
- bad code readability
- Catalyst is blind when performing optimizations
- impossibility to track data lineage of the transformation (a key aspect 
for the financial industry, see [Spline](https://absaoss.github.io/spline/) and 
[Spline 
paper](https://github.com/AbsaOSS/spline/releases/download/release%2F0.2.7/Spline_paper_IEEE_2018.pdf))

So my colleagues and I decided to extend the current Spark SQL API with 
well-known collection functions like concat, flatten, zipWithIndex, etc. We 
don't want to keep this functionality just in our fork of Spark, but would like 
to share it with others.
