Subject [jira] [Created] (HDFS-9321) Expose dispatcher parameters
Date Tue, 27 Oct 2015 23:21:27 GMT
Rafal Wojdyla created HDFS-9321:
-----------------------------------

             Summary: Expose dispatcher parameters
                 Key: HDFS-9321
                 URL: https://issues.apache.org/jira/browse/HDFS-9321
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: balancer & mover, HDFS
    Affects Versions: 2.7.1
            Reporter: Rafal Wojdyla
            Assignee: Rafal Wojdyla


To balance our cluster faster it was helpful to tune some hardcoded settings from dispatcher
- which is used by balancer. Including:
 * max number of no-pending-move iterations
 * max iteration time
 * source wait time

This patch adds exposes those parameters via configuration keys.
