Maxim Gekk created SPARK-26309:
----------------------------------
Summary: Verification of Data source options
Key: SPARK-26309
URL: https://issues.apache.org/jira/browse/SPARK-26309
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Maxim Gekk
Currently, applicability of datasource options passed to DataFrameReader and
DataFrameWriter are not checked fully. For example, If an option is used only
in write, it will be silently ignored in read. Such behavior of built-in
datasource usually confuses users. The ticket aims to implement additional
verification of datasource option and detect option misusing.
