------------------------------
FAILURE: Integrated in Hadoop-Mapreduce-trunk-Java8 #80 (See
[https://builds.apache.org/job/Hadoop-Mapreduce-trunk-Java8/80/])
HDFS-5631. Change BlockMetadataHeader.readHeader(..), ChunkChecksum class and
constructor to public; and fix FsDatasetSpi to use generic type instead of
FsVolumeImpl. Contributed by David Powell and Joe Pallas (szetszwo: rev

> Expose interfaces required by FsDatasetSpi implementations

> Key: HDFS-5631
> URL: https://issues.apache.org/jira/browse/HDFS-5631
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: 3.0.0
> Reporter: David Powell
> Assignee: Joe Pallas
> Priority: Minor
> Fix For: 3.0.0

>
> 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.
