Matt Burgess updated NIFI-4071:
-------------------------------
Priority: Minor (was: Major)
> ConvertJSONToSQL does not support Hive
> --------------------------------------
>
> Key: NIFI-4071
> URL: https://issues.apache.org/jira/browse/NIFI-4071
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Matt Burgess
> Priority: Minor
>
> Currently, the ConvertJSONToSQL processor does not support Hive as the target
> database, either using a HiveConnectionPool or a DBCPConnectionPool
> configured with a Hive driver. At the very least:
> 1) A SQLException occurs when determining the auto-increment value. This is
> due to a Hive bug (HIVE-13528
> [https://issues.apache.org/jira/browse/HIVE-13528]) where the column is not
> named according to the spec
> ([http://docs.oracle.com/javase/8/docs/api/java/sql/DatabaseMetaData.html#getColumns-java.lang.String-java.lang.String-java.lang.String-java.lang.String-]).
> 2) Column names are returned with the table name prepended (using a dot
> separator)
> 3) There may be other JDBC API calls that are not supported by the Hive JDBC
> driver.
> #1 could be solved by checking for "IS_AUTOINCREMENT" then failing over to
> "IS_AUTO_INCREMENT". #2 could be solved with a lastIndexOf("."), as is done
> in _org.apache.nifi.util.hive.HiveJdbcCommon#createSchema(java.sql.ResultSet,
> java.lang.String)_. #3 would take some investigation into the other JDBC API
> calls being made.
