Subject [jira] [Created] (HDFS-8538) Change the default volume choosing policy to AvailableSpaceVolumeChoosingPolicy
Date Thu, 04 Jun 2015 23:02:39 GMT
Andrew Wang created HDFS-8538:
---------------------------------

             Summary: Change the default volume choosing policy to AvailableSpaceVolumeChoosingPolicy
                 Key: HDFS-8538
                 URL: https://issues.apache.org/jira/browse/HDFS-8538
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.7.0
            Reporter: Andrew Wang
            Assignee: Andrew Wang


For datanodes with different sized disks, they almost always want the available space policy.
Users with homogenous disks are unaffected.

Since this code has baked for a while, let's change it to be the default.
