Moving forward, all patches won't be backward compatible. > Improve datanode shutdown latency > --------------------------------- > > Key: HDFS-15618 > URL: https://issues.apache.org/jira/browse/HDFS-15618 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode > Reporter: Ahmed Hussein > Assignee: Ahmed Hussein > Priority: Major > Fix For: 3.4.0 > > Attachments: HDFS-15618.001.patch, HDFS-15618.002.patch, > HDFS-15618.003.patch, HDFS-15618.004.patch > > > The shutdown of Datanode is a very long latency. 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
