----------------------------------
Summary: Use TextFileFormat in implementation of JsonFileFormat
and CSVFileFormat
Key: SPARK-18362
URL: https://issues.apache.org/jira/browse/SPARK-18362
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Josh Rosen
Assignee: Josh Rosen
Spark's CSVFileFormat and JsonFileFormat data sources use inefficient methods
for reading files during schema inference and do not benefit from file listing
/ IO performance improvements made in Spark 2.0. In order to fix this
performance problem, we should re-implement those read paths in terms of
TextFileFormat.
