Hans Fischer created SPARK-11214:
------------------------------------
Summary: Join with Unicode-String results wrong empty
Key: SPARK-11214
URL: https://issues.apache.org/jira/browse/SPARK-11214
Project: Spark
Issue Type: Bug
Components: PySpark, SQL
Affects Versions: 1.5.0
Reporter: Hans Fischer
Priority: Critical
I created a join that should clearly result in a single row but return: empty.
Could someone validate this bug?
hiveContext.sql('SELECT * FROM (SELECT "c" AS a) AS a JOIN (SELECT "c" AS b) AS
b ON a.a = b.b').take(10)
result: []
kind regards
Hans
