URL: https://issues.apache.org/jira/browse/SPARK-26151
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Maxim Gekk
Currently, CSV datasource and from_csv returns a rows with all nulls for bad
CSV records in the PERMISSIVE mode even some of fields were parsed and
converted successfully. For example, the CSV input:
{code}
0,2013-111-11 12:13:14
1,1983-08-04
{code}
for the first line returned row is Row(null, null) but value 0 can be parsed
and converted successfully. And result can be Row(0, null). This ticket aims to
change implementation of UnivocityParser and return the partial result.
