Description

WARN [pool-6-thread-2] metastore.PersistenceManagerProvider: datanucleus.autoStartMechanismMode is set to unsupported value null . Setting it to value: ignored

This does not need to be a WARN level logging for this scenario. Perhaps if user configures the value to some non-null value, then emit a warning, otherwise, simply emit an INFO level stating that the configuration is not set and that a reasonable default value will be used.
