Subject [jira] [Created] (HDFS-8890) Allow admin to specify which blockpools the balancer should run on

Chris Trezzo created HDFS-8890:
----------------------------------

             Summary: Allow admin to specify which blockpools the balancer should run on
                 Key: HDFS-8890
                 URL: https://issues.apache.org/jira/browse/HDFS-8890
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Chris Trezzo
            Assignee: Chris Trezzo


Currently the balancer runs on all blockpools. Allow an admin to run the balancer on a set
of blockpools. This will enable the balancer to skip blockpools that should not be balanced.
For example, a tmp blockpool that has a large amount of churn.

An example of the command line interface would be an additional flag that specifies the blockpools
by id:

-blockpools BP-6299761-10.55.116.188-1415904647555,BP-47348528-10.51.120.139-1415904199257
