Subject [jira] [Updated] (HDFS-9739) DatanodeStorage.isValidStorageId() is broken
Date Tue, 02 Feb 2016 20:22:39 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HDFS-9739:
--------------------------------
    Attachment: HDFS-9739.000.patch

The v0 patch simply adds the {{UUID.fromString}} back.

I think we any unit tests that can cover this will be very helpful. Any suggestion [~kihwal]?

> After HDFS-8979, the check is returning true for the old storage ID format. So storage
IDs in the old format  won't be updated during datanode upgrade.
