Hi I am using NiFi DistributedMapCacheServer to keep track of processed files in my flow. The issue is that we are working in a cluster and to leverage it we are using load balancing in queues so Flowfiles are not on the same node. Once they are arriving to Put/GetDistributedMapCache that is using DistributedMapCacheClient with fixed name of one of the hosts it only works when arriving Flowfile is on the same node as the one specified in DistributedMapCacheClient- for others we are getting:
FetchDistributedMapCache[id=d4713096-5ae5-1cb4-b777-202948e39e50] Unable to communicate with cache when processing StandardFlowFileRecord[uuid=5b1e8092-5bc5-4213-97a3-fa023691973f,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1587393798960-14, container=default, section=14], offset=983015, length=5996],offset=0,name=bf15d684-4100-4aa5-9fb5-fa0ddb21b140,size=5996] due to No route to host: java.net.NoRouteToHostException: No route to host
Is there any way to set up DMC server/client to work in such case, or can I somehow route all flowfiles to explicitly given node?
