Subject [jira] [Updated] (HDFS-8585) Remove dataBlockNum and parityBlockNum from StripedBlockProto
Date Fri, 12 Jun 2015 07:28:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8585?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yi Liu updated HDFS-8585:
-------------------------
    Attachment: HDFS-8585-HDFS-7285.001.patch

This JIRA remove {{dataBlockNum}} and {{parityBlockNum}} from StripedBlockProto,  also we
can remove {{StripedBlockProto}}, if we have some special things for striped, we can put it
in {{StripedBlocksFeature}}, since all them should be the same for the striped file.

This JIRA also fix a bug for {{FSImageLoader#getFileSize}}, we actually just need to calculate
the file size, should not count the parity block size, as we only count one replication block
size for contiguous block.

{{ECSchema}}, so we also need it from {{StripedBlockProto}}.
