Subject [jira] [Updated] (HDFS-5631) Expose interfaces required by FsDatasetSpi implementations
Date Mon, 02 Feb 2015 19:32:35 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Joe Pallas updated HDFS-5631:
    Attachment: HDFS-5631-branch-2.patch

I'd love to blame git, but it looks like I was actually bitten by a bug in SourceTree.

New patch is attached.

> This sub-task addresses section 4.1 of the document attached to HDFS-5194,
> the exposure of interfaces needed by a FsDatasetSpi implementation.
> Specifically it makes ChunkChecksum public and BlockMetadataHeader's
> readHeader() and writeHeader() methods public.
> The changes to BlockReaderUtil (and related classes) discussed by section
> 4.1 are only needed if supporting short-circuit, and should be addressed
> as part of an effort to provide such support rather than this JIRA.
> To help ensure these changes are complete and are not regressed in the
> future, tests that gauge the accessibility (though *not* behavior)
> of interfaces needed by a FsDatasetSpi subclass are also included.
> These take the form of a dummy FsDatasetSpi subclass -- a successful
> compilation is effectively a pass.  Trivial unit tests are included so
> that there is something tangible to track.
