Subject [jira] [Updated] (HDFS-9550) DiskBalancer: Add Run Command
Date Fri, 11 Dec 2015 22:21:46 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiaobing Zhou updated HDFS-9550:
--------------------------------
    Description: Run is kind of window dressing command that wraps report, plan and execute
commands to make it easy for a user to run disk balancer.  (was: 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
)
