Mithun Radhakrishnan created HIVE-14274:
-------------------------------------------
Summary: When columns are added to structs in a Hive table,
HCatLoader breaks.
Key: HIVE-14274
URL: https://issues.apache.org/jira/browse/HIVE-14274
Project: Hive
Issue Type: Bug
Components: HCatalog
Affects Versions: 2.1.0, 1.2.1
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
Consider this sequence of table/partition creation and schema evolution:
{code:sql}
-- Create table.
CREATE EXTERNAL TABLE `simple_text` (
foo STRING,
bar STRUCT<goo:STRING,moo:STRING>
)
PARTITIONED BY ( dt STRING )
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
COLLECTION ITEMS TERMINATED BY ':'
STORED AS TEXTFILE ;
-- Add partition.
ALTER TABLE simple_text ADD PARTITION ( dt='0' );
-- Alter the struct-column to add a new sub-field.
ALTER TABLE simple_text CHANGE COLUMN bar bar STRUCT<goo:STRING, moo:STRING,
zoo:STRING>;
{code}
The {{dt='0'}} partition's schema indicates 2 fields in {{bar}}. The data can
be read using Hive, but not through HCatLoader. The error looks as follows:
