With thousand+ node clusters, where > there might be machines added and removed regularly for maintenance, any > option to monitor and debug decommissioning status is very helpful. Proposal > here is to add suboptions to {{listOpenFiles}} for the above case. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
