> Ambari agent's {{FileCache}} is not thread-safe, hence needs to be disabled
> if {{parallel_execution}} is enabled. The server's
> {{agent.auto.cache.update=false}} setting is not enough to prevent all
> subprocesses from using the file cache, because they are started before the
> setting is received from the server.
