             Summary: Ozone: Ozone data placement is not even
                 Key: HDFS-12461
                 URL: https://issues.apache.org/jira/browse/HDFS-12461
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Anu Engineer
            Priority: Blocker


On a machine with 3 data disks, Ozone keeps on picking the same disk to place 
all containers. Looks like we have a bug in the round robin selection of disks.

Steps to Reproduce:
1. Install an Ozone cluster.
2. Make sure that datanodes have more than one disk.
3. Run corona few times, each run creates more containers.
4. Login into the data node.
5. Run a command like tree or ls -R /data or independently verify each location.
