Nifi 1.12.1 Wait/Notify Error

[#1]

Can anyone kindly help me to solve the below error from wait and notify processors?

"Notify[id=25d611ee-3783-1bb3-82d5-617707e6a53ea] failed to process session due to Remote cache server doesn't support protocol version 2;
Processor Administratively Yielded for 1 sec: java.lang.UnsupportedOperationException: Remote cache server doesn't support protocol version 2"

Hi @Karthik_Sise,

Are you using DistributedMapCacheServer(DMCS) controller service along with the DistributedMapCacheClientService(DMCCS) controller service. If not, please add that DMCS too. Note that, port configuration in DMCS should be the same port that is being using by DMCCS. It doesn't matter where you add as long as both DMCS and DMCCS are using the same port.
