             Summary: Interleaving CRC for ChunksData
                 Key: HDDS-284
                 URL: https://issues.apache.org/jira/browse/HDDS-284
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Bharat Viswanadham
            Assignee: Shashikant Banerjee


This Jira is to add CRC for chunks data.

Right now, in chunkInfo, data is just byte array. We want to change this as below:

_message Data {_

_required string magic =”Tullys00” = 1;_

 _required CRCTYPE crcType =_ _2__;_

_optional String LegacyMetadata = 3; // Fields to support inplace data migration_

_optional String LegacyData = 4;_

_optional ushort ChecksumblockSize = 5; // Size of the block used to compute the checksums_

_repeated uint32 checksums = 6 ; // Set of Checksums_ 

*_repeated byte data = 6;_*  _// Actual Data stream_

 

_}_

 

_This will help in error detection for containers during container scanner._
