tomscut created HDFS-16331: ------------------------------ Summary: Make dfs.blockreport.intervalMsec reconfigurable Key: HDFS-16331 URL: https://issues.apache.org/jira/browse/HDFS-16331 Project: Hadoop HDFS Issue Type: New Feature Reporter: tomscut Assignee: tomscut Attachments: image-2021-11-18-09-33-24-236.png, image-2021-11-18-09-35-35-400.png
We have a cold data cluster, which stores as EC policy. There are 24 fast disks on each node and each disk is 7 TB. Recently, many nodes have more than 10 million blocks, and the interval of FBR is 6h as default. Frequent FBR caused great pressure on NN. !image-2021-11-18-09-35-35-400.png|width=491,height=337! !image-2021-11-18-09-33-24-236.png|width=912,height=256! We want to increase the interval of FBR, but have to rolling restart the DNs, this operation is very heavy. In this scenario, it is necessary to make _dfs.blockreport.intervalMsec_ reconfigurable. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
