> Syncing metastore table with serde schema
> -----------------------------------------
>
> Key: HIVE-15995
> URL: https://issues.apache.org/jira/browse/HIVE-15995
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 1.2.1, 2.1.0, 3.0.0
> Reporter: Michal Ferlinski
> Assignee: Adam Szita
> Priority: Major
> Attachments: HIVE-15995.1.patch, HIVE-15995.2.patch,
> HIVE-15995.3.patch, HIVE-15995.4.patch, HIVE-15995.5.patch, HIVE-15995.patch,
> cx1.avsc, cx2.avsc
>
>
> Hive enables table schema evolution via properties. For avro e.g. we can
> alter the 'avro.schema.url' property to update table schema to the next
> version. Updating properties however doesn't affect column list stored in
> metastore DB so the table is not in the newest version when returned from
> metastore API. This is problem for tools working with metastore (e.g. Presto).
> To solve this issue I suggest to introduce new DDL statement syncing
> metastore columns with those from serde:
> {code}
> ALTER TABLE user_test1 UPDATE COLUMNS
> {code}
> Note that this is format independent solution.
> To reproduce, follow the instructions below:
> - Create table based on avro schema version 1 (cxv1.avsc)
> {code}
> CREATE EXTERNAL TABLE user_test1
> PARTITIONED BY (dt string)
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat'
> LOCATION
> '/tmp/schema-evolution/user_test1'
> TBLPROPERTIES ('avro.schema.url'='/tmp/schema-evolution/cx1.avsc');
> {code}
> - Update schema to version 2 (cx2.avsc)
> {code}
> ALTER TABLE user_test1 SET TBLPROPERTIES ('avro.schema.url' =
> '/tmp/schema-evolution/cx2.avsc');
> {code}
> - Print serde columns (top info) and metastore columns (Detailed Table
> Information):
> {code}
> DESCRIBE EXTENDED user_test1
> {code}
