-----------------------------------
Summary: from_json in FAILFAST mode doesn't fail fast, instead it
just returns nulls
Key: SPARK-23194
URL: https://issues.apache.org/jira/browse/SPARK-23194
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.0
Reporter: Burak Yavuz
from_json accepts Json parsing options such as being PERMISSIVE to parsing
errors or failing fast. It seems from the code that even though the default
option is to fail fast, we catch that exception and return nulls.
In order to not change behavior, we should remove that try-catch block and
change the default to permissive, but allow failfast mode to indeed fail.
