-------------------------------------
Summary: NullPointerException running hive query with array
dereference in select and where clause
Key: SPARK-12930
URL: https://issues.apache.org/jira/browse/SPARK-12930
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.5.2
Reporter: Thomas Graves
I had a user doing a hive query from spark where they had a array dereference
in the select clause and in the where clause, it gave the user a
NullPointerException when the where clause should have filtered it out. Its
like spark is evaluating the select part before running the where clause. The
info['pos'] below is what caused the issue:
Query looked like:
SELECT foo,
info['pos'] AS pos
FROM db.table
WHERE date >= '$initialDate' AND
date <= '$finalDate' AND
info is not null AND
info['pos'] is not null
LIMIT 10
