Jira :- https://issues.apache.org/jira/browse/HADOOP-19604 BlockId computation to be consistent across clients for PutBlock and PutBlockList so made use of blockCount instead of offset. Block IDs were previously derived from the data offset, which could lead to inconsistency across different clients. The change now uses blockCount (i.e., the index of the block) to compute the Block ID, ensuring deterministic and consistent ID generation for both PutBlock and PutBlockList operations across clients. Restrict URL encoding of certain JSON metadata during setXAttr calls. When setting extended attributes (xAttrs), the JSON metadata (hdi_permission) was previously URL-encoded, which could cause unnecessary escaping or compatibility issues. This change ensures that only required metadata are encoded. Maintain the MD5 hash of the whole block to validate data integrity during flush. During flush operations, the MD5 hash of the entire block's data is computed and stored. This hash is later used to validate that the block correctly persisted, ensuring data integrity and helping detect corruption or transmission errors. -- This is an automated message from the Apache Git Service.
