tomscut opened a new pull request #3753: URL: https://github.com/apache/hadoop/pull/3753
JIRA: [HDFS-16371](https://issues.apache.org/jira/browse/HDFS-16371). Currently, the datanode can detect slow disks. See [HDFS-11461](https://issues.apache.org/jira/browse/HDFS-11461). And after [HDFS-16311](https://issues.apache.org/jira/browse/HDFS-16311), the slow disks metrics we collected is more accurate. So we can exclude these slow disks according to some rules when choosing volume. This will prevents some slow disks from affecting the throughput of the whole datanode. -- This is an automated message from the Apache Git Service.
