> 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
> Attachments: HDFS-5631-LazyPersist.patch,
> HDFS-5631-LazyPersist.patch, HDFS-5631.patch, HDFS-5631.patch
>
>
> 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.
