> Ambari MetaInfo manager has not loaded the "timelineAppId" field from the
> metainfo.xml belonging to the NiFi service in the HDF management pack (which
> by default set to 'nifi') . Hence the default metrics appId used is the
> component name (NIFI_MASTER) however NiFi metrics data is stored with a
> different app id. This leads to no metrics being displayed on the NiFi
> summary screen.
