[jira] [Assigned] (HDFS-5631) Expose interfaces required by FsDatasetSpi implementations
[ https://issues.apache.org/jira/browse/HDFS-5631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Joe Pallas reassigned HDFS-5631: Assignee: Joe Pallas (was: David Powell) 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.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
