Currently, the default value of "dfs.federation.router.mount-table.cache.enable" is true and the default value of "dfs.federation.router.mount-table.max-cache-size" is 10000. But there is no metric that display cache hit rate, I think we can add a hit rate metric to watch the Cache performance and better tuning the parameters. -- This is an automated message from the Apache Git Service.
