# Using the attached flow template first enable and run the flow. This should
exercise the cache.
# run `nifi.sh diagnostics --verbose` and save the file
# Disable and delete the controller services
# run `nifi.sh diagnostics --verbose` and save the file with a different name
# compare the thread dumps. The second file should not have any threads
related to the DistributedMapCacheClientService but it will.
# repeat step 1 and 2, and look at the thread dump again. There should be
threads from two separate DistributedMapCacheClientServices like this:
