A block scanner waits for 5 > minutes to join on each VolumeScanner thread. > Since the scanners are daemon threads and do not alter the block content, it > is safe to ignore such conditions on shutdown of Datanode. -- 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
