hadoop - create a Parquet backed Hive table by using a schema file -


cloudera documentation, shows simple way "create avro backed hive table using avro schema file." works great. same thing parquet backed hive table, relevant documentation in case lists out every column type rather reading schema. possible read parquet columns schema, in same way avro data?

currently, answer appears no. there open issue hive. https://issues.apache.org/jira/browse/parquet-76

the issue has been active recently, in near future hive offer same functionality parquet avro.
