----------------------------------------------
Summary: Create HiveJdbcDatabaseAccessor for JDBC storage handler
Key: HIVE-23302
URL: https://issues.apache.org/jira/browse/HIVE-23302
Project: Hive
Issue Type: Bug
Components: StorageHandler
Reporter: Jesus Camacho Rodriguez
The {{JdbcDatabaseAccessor}} associated with the storage handler makes some SQL
calls to the RDBMS through the JDBC connection. There is a
{{GenericJdbcDatabaseAccessor}} with a generic implementation that the storage
handler uses if there is no specific implementation for a certain RDBMS.
Currently, Hive uses the {{GenericJdbcDatabaseAccessor}}. Afaik the only
generic query that will not work is splitting the query based on offset and
limit, since the syntax for that query is different than the one accepted by
Hive. We should create a {{HiveJdbcDatabaseAccessor}} to override that query
and possibly fix any other existing incompatibilities.
