Szehon Ho updated HIVE-6575:
----------------------------
Description:
Create parquet table with map and run select * from parquet_table, returns
following exception:
{noformat}
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
{noformat}
However select <mapcol> from parquet_table seems to work, and thus joins will
work.
