-----------------------------------
Assignee: Michael Armbrust
> [SQL] Self join with ArrayType columns problems
> -----------------------------------------------
>
> Key: SPARK-5454
> URL: https://issues.apache.org/jira/browse/SPARK-5454
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.2.0
> Reporter: Pierre Borckmans
> Assignee: Michael Armbrust
> Priority: Blocker
> Fix For: 1.3.0
>
>
> Weird behaviour when performing self join on a table with some ArrayType
> field. (potential bug ?)
> I have set up a minimal non working example here:
> https://gist.github.com/pierre-borckmans/4853cd6d0b2f2388bf4f
> In a nutshell, if the ArrayType column used for the pivot is created manually
> in the StructType definition, everything works as expected.
> However, if the ArrayType pivot column is obtained by a sql query (be it by
> using a "array" wrapper, or using a collect_list operator for instance), then
> results are completely off.
