----------------------------------
Summary: Read zipped CSV and JSON files
Key: SPARK-25513
URL: https://issues.apache.org/jira/browse/SPARK-25513
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Maxim Gekk
Spark can read compression files if there is compression codec for them. By
default, Hadoop provides compressors/decompressors for bzip2, deflate, gzip,
lz4 and snappy but they cannot be used directly for reading zip archives.
In general zip archives can contain multiple entries but in practice users use
zip archives to store only one file. This use case is pretty often in wild.
The ticket aims to support reading of zipped CSV and JSON files in multi-line
mode when each zip archive contains only one file.
