Neha Tomar commented on HIVE-2443:
----------------------------------
Sorry. Forgot to metion. I meant "Can you please let me know if user defined
delimiters are supported for nested complex types with hive 0.9.0?"
> Wrong delimiter is getting picked up for structs inside an array.

> Key: HIVE-2443
> URL: https://issues.apache.org/jira/browse/HIVE-2443
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Reporter: Thulasi Ram Naidu P
> Priority: Minor
>
> I am trying to create table with multiple level of delimiters. But the
> default LazySimpleSerDe doesn't pick up the second serializer for serializing
> a struct inside an array which I specified using COLLECTION ITEMS DELIMITED
> BY.
> My table looks like this:
> create external table if not exists mytable(col1 bigint, col2 string,
> col3 string, col4 double, col5 double, col6 double, col7 double, col8
> array<struct<id1:string, id2:string, id3:string, id4:string,
> id5:int>>)
> ROW FORMAT DELIMITED
> FIELDS TERMINATED BY '\t'
> COLLECTION ITEMS TERMINATED BY ',:'
> Location '<FILEPATH>';
> Input data:
> 123456 XYZ1 RANDOM 1 1 1 1
> x1:y1:z1:w1:5,x2:y2:z2:w1:5
> When I do "Select * from mytable" I am expecting output to be
> 123456 XYZ1 RANDOM 1.0 1.0 1.0 1.0
> [{"id1":"x1","id2":"y1","id3":"z1","id4":"w1","id5":5},{"id1":"x2","id2":"y2","id3":"z2","id4":"w1","id5":5}]
> However, it is returning,
> 123456 XYZ1 RANDOM 1.0 1.0 1.0 1.0
> [{"id1":"x1:y1:z1:w1:5","id2":null,"id3":null,"id4":null,"id5":null},{"id1":"x2:y2:z2:w1:5","id2":null,"id3":null,"id4":null,"id5":null}]
> But when I changed the schema of table as
> create external table if not exists mytable(col1 bigint, col2 string,
> col3 string, col4 double, col5 double, col6 double, col7 double, col8
> array<struct<id1:string, id2:string, id3:string, id4:string,
> id5:int>>)
> ROW FORMAT DELIMITED
> FIELDS TERMINATED BY '\t'
> COLLECTION ITEMS TERMINATED BY ','
> MAP KEYS TERMINATED BY ':'
> Now the select query is returning the values correctly.
