[jira] [Created] (HDFS-15004) Refactor TestBalancer for faster execution.

Konstantin Shvachko created HDFS-15004:
------------------------------------------

             Summary: Refactor TestBalancer for faster execution.
                 Key: HDFS-15004
                 URL: https://issues.apache.org/jira/browse/HDFS-15004
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs, test
    Affects Versions: 2.10.0
            Reporter: Konstantin Shvachko


{{TestBalancer}} is a big test by itself, it is also a part of many other tests. Running these tests involves spinning of {{MiniDFSCluter}} and shutting it down for every test case, which is inefficient. Many of the test cases can run using the same instance of {{MiniDFSCluter}}, but not all of them. Would be good to refactor the tests to optimize their running time.
