However there are different > scenarios when backoff could happen. Currently there is no way to > differenciate whether a backoff happened due to lowest prio+disconnection or > queue overflow from higher priority queues when connection between client and > namenode remains open. Currently IPC server just emits a single metrics for > all the backoffs. > Example: > # Client are directly enqueued into lowest priority queue and backoff when > lowest queue is full. Client are expected to disconnect from namenode. > # Client are enqueued into non-lowest priority queue and overflowed all the > way down to lowest priority queue and back off. In this case, connection > between client and namenode remains open. > We would like to add metrics for #1 -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
