For nifi, we have jvm options in bootstrap.conf: java.arg.2=-Xms512m
java.arg.3=-Xmx512m Then we also have env variables(got to know on google search,not from official documentation) that can be set from outside(like from kubernetes config yaml): NIFI_JVM_HEAP_INIT
NIFI_JVM_HEAP_MAX What's the connection between these 2 sets of properties?

I have nifi running in openshift, and observe that after some time of operation a dialog box pops up on nifi UI, containing following message, and pod restarts. Application is not available The application is currently not serving requests at this endpoint. It may not have been started or is still starting.
Possible reasons you are seeing this page: The host doesn't exist. Make sure the hostname was typed correctly and that a route matching this hostname exists.
The host exists, but doesn't have a matching path. Check if the URL path was typed correctly and that the route was created using the desired path.
Route and path matches, but all pods are down. Make sure that the resources exposed by this route (pods, services, deployment configs, etc) have at least one pod running. nifi logs dont show anything related to it though. What can be the possible issue here?

In nifi, we set java memory configurations(Xms, Xmx) in bootstrap.conf. Is it possible to set it via kubernetes yaml? I tried with 'args' or with env variable JDK_JAVA_OPTIONS/JAVA_TOOL_OPTIONS , but none works.

I have a flow usecase wherein I use RouteOnAttribute to route to FetchFile. FetchFile processor is then supposed to read a file from a directory and send it to PutSFTP processor. But I observe that file routed from RouteOnAttribute to FetchFile is what is forwarded to PutSFTP. What I want is that FetchFile forwards that file to PutSFTP that it reads from directory. Is it possible?

FetchFile processor has property 'Move Conflict Strategy': Basically its about file conflict in destination folder. But it doesn't have any property for destination folder, and correctly so as this processor is only about pulling a file in nifi system. So why is this property needed?

This is RouteOnAttribute processor. As you can see I have 2 properties defined. I want to use fileTransfer property to route to GetFile processor. And this is connection dialog box for one of the existing connections, and it lists 'fileTransfer' as a relationship.
