tomscut created HDFS-16076: ------------------------------ Summary: Avoid using slow DataNodes for reading by sorting locations Key: HDFS-16076 URL: https://issues.apache.org/jira/browse/HDFS-16076 Project: Hadoop HDFS Issue Type: Improvement Reporter: tomscut Assignee: tomscut

This reduces the probability that slow nodes will be used for reading. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
