> A Null Pointer Exception occurs when inserting data with 'distribute by' clause. The following snippet query reproduces this issue:
> *(non-vectorized , non-llap mode)*
> {code:java}
> create table table1 (col1 string, datekey int);
> insert into table1 values ('ROW1', 1), ('ROW2', 2), ('ROW3', 1);
> create table table2 (col1 string) partitioned by (datekey int);
> set hive.vectorized.execution.enabled=false;
> set hive.optimize.sort.dynamic.partition=true;
> set hive.exec.dynamic.partition.mode=nonstrict;
> insert into table table2
> PARTITION(datekey)
> select col1,
> datekey
> from table1
> distribute by datekey ;
> {code}
> I could run the insert query without the error if I remove Distribute By or use Cluster By clause.
> It seems that the issue happens because Distribute By does not guarantee clustering or sorting properties on the distributed keys.
> FileSinkOperator removes the previous fsp. FileSinkOperator will remove the previous fsp which might be re-used when we use Distribute By.
