>
> When the node startup, NiFi will create processor and load the property &
> state.
> But ListHDFS will ignore the previous listed-state stored on Zookeeper, and
> relist all file again.
>
> And I found when we call the function setProperty, we only check the value
> between default and newValue. If oldValue is same with newValue, it'll also
> trigger function onPropertyModified.
> It casue ListHDFS loaclVariable: resetState to be true. When ListHDFS be
> triggered, it'll clear the state empty, and relist all the files in the
> directory.
>
> {code:java}
> // AbstractComponentNode.java
> if (!value.equals(propertyModComparisonValue)) {
> try {
> onPropertyModified(descriptor, oldValue, value);
> } catch (final Exception e) {
> // nothing really to do here...
> }
> }
> {code}
