Subject [jira] Updated: (HDFS-1693) TestDFSStorageStateRecovery fails
Date Wed, 02 Mar 2011 18:42:36 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1693?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suresh Srinivas updated HDFS-1693:
----------------------------------

    Attachment: HDFS-1693.patch

Changes:
# Added a test case for testing the recovery of block pool storage.
# MiniDFSCluster is enhanced to provide various storage directories. Hardcoding of current,
rbw, finalized etc for
directory path names is removed.
# UpgradeUtilities has a separate set of methods for manipulating storage directories, instead
of basing it on NodeType
parameter. This makes these methods to evolve independently. Also needed since NodeType currently
cannot describe a
block pool.

With the change all the following upgrade related tests pass:
# TestDFSStorageStateRecovery
# TestDFSFinalize
# TestDFSRollback
# TestDFSStartupVersions
# TestDFSUpgrade
# TestDFSUpgradeFromImage

> The test tests recovery of a datanode by setting up different combination of directories
under storage directory -
> current, previous, previous.tmp, removed.tmp etc.
> This test needs to be fixed and enhanced to add recovery for block pool storage along
with existing datanode storage.
