> 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
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
