Attila Doroszlai created HDDS-2238: -------------------------------------- Summary: Container Data Scrubber spams log in empty cluster Key: HDDS-2238 URL: https://issues.apache.org/jira/browse/HDDS-2238 Project: Hadoop Distributed Data Store Issue Type: Sub-task Components: Ozone Datanode Affects Versions: 0.5.0 Reporter: Attila Doroszlai Assignee: Attila Doroszlai
In an empty cluster (without closed containers) logs are filled with messages from completed data scrubber iterations (~3600 per second for me), if Container Scanner is enabled ({{hdds.containerscrub.enabled=true}}), eg.: {noformat} datanode_1 | 2019-10-03 15:43:57 INFO ContainerDataScanner:114 - Completed an iteration of container data scrubber in 0 minutes. Number of iterations (since the data-node restart) : 6763, Number of containers scanned in this iteration : 0, Number of unhealthy containers found in this iteration : 0 {noformat} Also CPU usage is quite high. I think: # there should be a small sleep between iterations # it should log only if any containers were scanned -- 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
