@Pierre Villard We are currently using Nifi 1.7 over 10 nodes where the nodes are distributed across two data centers. The design uses an external Zookeeper. However, we are facing a problem where the Primary Co-ordinator being elected at random by the Zookeeper across both the data centers, and electing particular servers as Primary having higher I/O and thus increasing the CPU while doing the List function.
