Subject [jira] [Updated] (HDFS-9850) DiskBalancer : Explore removing references to FsVolumeSpi
Date Wed, 28 Sep 2016 00:43:20 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Manoj Govindassamy updated HDFS-9850:
-------------------------------------
    Attachment: HDFS-9850.004.patch

Attaching v04 patch to address following. [~anu], kindly take a look.
* Restored old behavior of getQueryStatus to return volume paths even if the volume is removed.
Made VolumePair to hold the volume paths.
* Accordingly changed the expectation in TestDiskBalancer. Test will not expect DiskBalancerException
and instead awaits for the status to reach PLAN_DONE.

> In HDFS-9671, [~arpitagarwal] commented that we should explore the possibility of removing
references to FsVolumeSpi at any point and only deal with storage ID. We are not sure if this
is possible, this JIRA is to explore if that can be done without issues.
