[jira] [Updated] (SPARK-32432) Add support for reading ORC/Parquet files with SymlinkTextInputFormat

     [ https://issues.apache.org/jira/browse/SPARK-32432?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Noritaka Sekiyama updated SPARK-32432:
--------------------------------------
    Description: 
Hive style symlink (SymlinkTextInputFormat) is commonly used in different analytic engines including prestodb and prestosql.

Currently SymlinkTextInputFormat works with JSON/CSV files but does not work with ORC/Parquet files in Apache Spark (and Apache Hive).

On the other hand, prestodb and prestosql support SymlinkTextInputFormat with ORC/Parquet files.

This issue is to add support for reading ORC/Parquet files with SymlinkTextInputFormat in Apache Spark.
