> To reproduce:
> {code}
> create table testarray (a array<string>);
> load data local inpath '/home/ahsu/test/array.txt' into table testarray;
> # create partitioned Avro table with one array column
> create table avroarray partitioned by (y string) row format serde 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
with serdeproperties ('avro.schema.literal'='{"namespace":"test","name":"avroarray","type":
"record", "fields": [ { "name":"a", "type":{"type":"array","items":"string"} } ] }')  STORED
as INPUTFORMAT  'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'  OUTPUTFORMAT
 'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat';
> insert into table avroarray partition(y=1) select * from testarray;
> # add an int column with a default value of 0
> alter table avroarray set serde 'org.apache.hadoop.hive.serde2.avro.AvroSerDe' with serdeproperties('avro.schema.literal'='{"namespace":"test","name":"avroarray","type":
"record", "fields": [ {"name":"intfield","type":"int","default":0},{ "name":"a", "type":{"type":"array","items":"string"}
} ] }');
> # fails with ClassCastException
> select * from avroarray;
> {code}
> The select * fails with:
> {code}
> Failed with exception java.io.IOException:java.lang.ClassCastException: org.apache.hadoop.hive.serde2.objectinspector.StandardListObjectInspector
cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector
> {code}
