Amithsha created HDFS-14264: ------------------------------- Summary: Datanode du -sk command is slow Key: HDFS-14264 URL: https://issues.apache.org/jira/browse/HDFS-14264 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 2.7.1 Reporter: Amithsha
Datanode consuming more time on du -sk command as well as creating heavy IO on disk. In our prod systems, each disk of dfs usage is 3Tb, to caculate it, the datanode will spend 10-20min Avg time. Also nodemanagers are running on the same box during this du -sk operation could see heavy IO on disk. Datanode should cache the usage and also not be cleared by any other process. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
