tianhang tang commented on HDFS-15822: -------------------------------------- [~kihwal] Tks for suggestion. Add some link. > Client retry mechanism may invalid when use hedgedRead > ------------------------------------------------------ > > Key: HDFS-15822 > URL: https://issues.apache.org/jira/browse/HDFS-15822 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs-client > Reporter: tianhang tang > Assignee: tianhang tang > Priority: Major > Attachments: HDFS-15822.001.patch > > > Hedgedread uses ignoreNodes to ensure that multiple requests fall on > different nodes. But the ignoreNodes never been cleared. So if the request of > 1st round all failed, and the refetched location is not changed, HDFS client > would not request the same nodes which are in the ignoreNodes. It just sleep > time by time until reach the retry num, then throw a exception. -- 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
