NameNode resolves the > client host's topology and uses it to sort the hosts where the blocks locate > in. Such topology will be cached so the next access will be efficient, while > if the standby NameNode is newly restarted, then all the client hosts, e.g., > YARN hosts need to be resolved. > Solutions can be: 1) we can expose an API in DFSAdmin to load topology cache, > or 2) we can add a new configuration in HDFS cluster to skip resolving > topology for non-colocated HDFS cluster. Since client hosts and HDFS hosts > are not colocated, it's unnecessary to sort the DataNodes for the clients. > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
