And we can set the dfs.federation.router.dn-report.time-out and > dfs.federation.router.dn-report.cache-expire to avoid time out. But when we > start the router, the FederationMetrics will also invoke the method to get > node usage. If time out error happened, we cannot adjust the parameter > time_out. And the time_out in the FederationMetrics and NamenodeBeanMetrics > should be the same. > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
