It is absolutely possible to do this. However somethings need to be considered: With a multi node Nifi cluster, the local storage must be a single location usually the primary node. This data will not be local to the rest of the cluster nodes. The location should be separate from OS partition and the required nifi repository partitions. This is to avoid corrupting these partitions in the chance local storage consumes all available space. In past projects I have used primary node, with a separate partition to storing files local to NiFi Primary Node. These files are then used outside of NiFi for other purposes. In some projects these files are picked up in NiFi in separate flows, and then re-distributed into the cluster for processing across all nodes. The primary use case here was audit received files directly to disk by Team 1. Some time later Team 2 access files for processing. In this sample Team 1 and Team 2 are completely separate with Security Group based access to nifi (they cannot see each others flows).
