> Erasure coding: recomputing block checksum on the fly by reconstructing the
> missed/corrupt block data
> -----------------------------------------------------------------------------------------------------
>
> Key: HDFS-9833
> URL: https://issues.apache.org/jira/browse/HDFS-9833
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Kai Zheng
> Assignee: Rakesh R
> Labels: hdfs-ec-3.0-must-do
> Attachments: HDFS-9833-00-draft.patch, HDFS-9833-01.patch
>
>
> As discussed in HDFS-8430 and HDFS-9694, to compute striped file checksum
> even some of striped blocks are missed, we need to consider recomputing block
> checksum on the fly for the missed/corrupt blocks. To recompute the block
> checksum, the block data needs to be reconstructed by erasure decoding, and
> the main needed codes for the block reconstruction could be borrowed from
> HDFS-9719, the refactoring of the existing {{ErasureCodingWorker}}. In EC
> worker, reconstructed blocks need to be written out to target datanodes, but
> here in this case, the remote writing isn't necessary, as the reconstructed
> block data is only used to recompute the checksum.
