select * fails on parquet table with map datatype

    XMLWordPrintableJSON

    Details

      Description

      Create parquet table with map and run select * from parquet_table, returns following exception:

       FAILED: RuntimeException java.lang.ClassCastException: org.apache.hadoop.hive.ql.io.parquet.serde.DeepParquetHiveMapInspector cannot be cast to org.apache.hadoop.hive.ql.io.parquet.serde.StandardParquetHiveMapInspector
      

      However select <mapcol> from parquet_table seems to work, and thus joins will work.
