[GitHub] [orc] cxzl25 commented on pull request #1458: ORC-1403: ORC supports reading empty field name

cxzl25 commented on PR #1458:
URL: https://github.com/apache/orc/pull/1458#issuecomment-1501124249

   > Does Apache Hive support empty field names?
   
   See https://github.com/apache/spark/pull/35253#issuecomment-1321866542.
   
   When `spark.sql.orc.impl=native`, writing to empty field name is supported, but reading is failed, when `spark.sql.orc.impl=hive`, neither writing nor reading empty field name is supported.
   
   Before ORC-529 1.6.0, ORC should support reading empty filed name.
