But if this > thread successfully finishes, DN does not record this {{IOError}}. > We need one measurement to count all {{IOErrors}} for each volume. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
