Cloudera Manager fails to upgrade Sqoop2 when parcels are enabled

Cloudera Manager fails to update the generic Sqoop2 connectors when parcels are enabled, and the Sqoop2 server won't start anymore. In the logs a error like:

Caused by: org.apache.sqoop.common.SqoopException: JDBCREPO_0026:Upgrade required but not allowed - Connector: generic-jdbc-connector

is shown.
This issue can be fixed by adding two properties into the service safety valve of sqoop:


This happen trough the missing autoupdate of the default sqoop connectors in Cloudera Manager. After the properties are added, SqoopServer should be able to update the drivers and will start sucessfully.
