Xiaobing Zhou created HDFS-9550: ----------------------------------- Summary: DiskBalancer: Add Run Command Key: HDFS-9550 URL: https://issues.apache.org/jira/browse/HDFS-9550 Project: Hadoop HDFS Issue Type: Sub-task Components: balancer & mover Affects Versions: 2.8.0 Reporter: Xiaobing Zhou Assignee: Xiaobing Zhou
This is to propose being able to query all the nodes that we send various plans to. In order to do the query, query 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 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)
