Description

For the NiFi UI, clarify the "?" balloon help for "Controller Settings" ---> GENERAL tab's "Maximum Timer Driven Thread Count" and "Maximum Event Driven Thread Count" settings. Currently, the explanations are valid for a stand-alone NiFi, but not a clustered-NiFi.

Maximum Timer Driven Thread Count = The maximum number of threads for timer driven processors available to the system.

Maximum Event Driven Thread Count = The maximum number of threads for event driven processors available to the system.

The can be confusing because the "Active Threads" value displayed on the Status Bar is actually for the entire system whether or not it is in a stand-alone or clustered formation. Perhaps the explanations for the settings should be something like

Maximum Timer Driven Thread Count = The maximum number of threads for timer driven processors available per node.

Maximum Event Driven Thread Count = The maximum number of threads for event driven processors available per node.
