Xiaobing Zhou updated HDFS-9462: -------------------------------- Resolution: Duplicate Status: Resolved (was: Patch Available) > DiskBalancer: Add Scan Command > ------------------------------ > > Key: HDFS-9462 > URL: https://issues.apache.org/jira/browse/HDFS-9462 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: balancer & mover > Affects Versions: 2.8.0 > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Attachments: HDFS-9462-HDFS-10576.001.patch, > HDFS-9462-HDFS-1312.000.patch, HDFS-9462.002.patch, HDFS-9462.003.patch, > HDFS-9462.004.patch > > > This is to propose being able to scan all the nodes that we send various > plans to. In order to do the scan, scan command will talk to all involved > data nodes through cluster interface(HDFS-9449) and data models(HDFS-9420) > and compare the hash tag that it gets back to make sure that the plan is that > we are interested in and print out the results. > As bonus, it should support the ability to print out the diff of what > happened when a DiskBalancer run is complete. Assuming the state of the > cluster is saved to file before.json. There should be two kinds of diffs: > 1. Overall what happened in the cluster vs. before.json -- just a summary > 2. for a specific node -- just like report command we should be able to pass > in a node and as see the changes against the before.json -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
