KUP-11529

class "string" is invalid for string external tables

Cause

An invalid value was specified for the COM.ORACLE.BIGDATA.CLASS access parameter for an ORACLE_HIVE or ORACLE_HDFS external table access driver. The ORACLE_HIVE and ORACLE_HDFS access drivers use a built-in class in order to access their data source.


Action

Omit the COM.ORACLE.BIGDATA.CLASS access parameter when creating an external table using the ORACLE_HIVE or ORACLE_HDFS access driver. Alternatively, the builtin class names, COM.ORACLE.BIGDATA.AD.HIVE and COM.ORACLE.BIGDATA.AD.HDFS, may be used when creating an external table using the ORACLE_HIVE or ORACLE_HDFS access driver.
