> Key: HDDS-284
> URL: https://issues.apache.org/jira/browse/HDDS-284
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Bharat Viswanadham
> Assignee: Hanisha Koneru
> Priority: Major
> Attachments: CRC and Error Detection for Containers.pdf,
> HDDS-284.00.patch, HDDS-284.005.patch, HDDS-284.01.patch, HDDS-284.02.patch,

>
> This Jira is to add CRC for chunks data.
>
>
> Right now a Chunk Info structure looks like this:
>
> _message ChunkInfo {_
> _required string chunkName =_ _1__;_
> _required uint64 offset =_ _2__;_
> _required uint64 len =_ _3__;_
> _optional string checksum =_ _4__;_
> _repeated KeyValue metadata =_ _5__;_
> _}_
>
> _Proposal is to change ChunkInfo structure as below:_
>
> _message ChunkInfo {_
> _required string chunkName =_ _1__;_
> _required uint64 offset =_ _2__;_
> _required uint64 len =_ _3__;_
> _optional bytes checksum =_ _4__;_
> _optional CRCType checksumType =_ _5__;_
> _optional string legacyMetadata =_ _6__;_
> _optional string legacyData =_ _7__;_
> _repeated KeyValue metadata =_ _8__;_
> _}_
>
> _Instead of changing disk format, we put the checksum, checksumtype and
> legacy data fields in to chunkInfo._
