--------------------------------------
Summary: COLUMNS_V2[COMMENT] size different between derby db &
other dbs.
Key: HIVE-21178
URL: https://issues.apache.org/jira/browse/HIVE-21178
Project: Hive
Issue Type: Bug
Reporter: Venu Yanamandra
Based on the sql scripts present for derby db, the size of COLUMNS_V2[COMMENT]
is 4000.
[https://github.com/apache/hive/tree/master/metastore/scripts/upgrade/derby]
However, if we see those present in say - mysql, we see them limited at 256.
[https://github.com/apache/hive/tree/master/metastore/scripts/upgrade/mysql]
For a requirement to store larger amount of comments, non-derby dbs, limit the
maximum size of the column comments.
Kindly review the discrepancy.
