Sathish updated HIVE-7850:
--------------------------
Description:
* Created a parquet file from the Avro file which have 1 array data type and
rest are primitive types. Avro Schema of the array data type. Eg:
{code}
{ "name" : "action", "type" : [ { "type" : "array", "items" : "string" },
"null" ] }
{code}
* Created External Hive table with the Array type as below,
{code}
create external table paraArray (action Array) partitioned by (partitionid int)
row format serde 'parquet.hive.serde.ParquetHiveSerDe' stored as inputformat
'parquet.hive.MapredParquetInputFormat' outputformat
'parquet.hive.MapredParquetOutputFormat' location '/testPara';
alter table paraArray add partition(partitionid=1) location '/testPara';
{code}
* Run the following query(select action from paraArray limit 10) and the Map
reduce jobs are failing with the following exception.
{code}
Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error
while processing row [Error getting row data with exception

This issue has long back posted on Parquet issues list and Since this is
related to Parquet Hive serde, I have created the Hive issue here, The details
and history of this information are as shown in the link here
https://github.com/Parquet/parquet-mr/issues/281.
