ZhangHB created HDFS-16882: ------------------------------ Summary: Add cache hit rate metric in MountTableResolver#getDestinationForPath Key: HDFS-16882 URL: https://issues.apache.org/jira/browse/HDFS-16882 Project: Hadoop HDFS Issue Type: Improvement Components: rbf Affects Versions: 3.3.4 Reporter: ZhangHB
Currently, the default value of "dfs.federation.router.mount-table.cache.enable" is ture, 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 message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
