Allow DFSClient to find out and use the CRC type being used for a file. -----------------------------------------------------------------------
Key: HDFS-3177 URL: https://issues.apache.org/jira/browse/HDFS-3177 Project: Hadoop HDFS Issue Type: Bug Components: data-node, hdfs client Affects Versions: 0.23.0 Reporter: Kihwal Lee Assignee: Kihwal Lee Fix For: 0.23.3, 2.0.0, 3.0.0 To support HADOOP-8060, DFSClient should be able to find out the checksum type being used for files in hdfs. In my prototype, DataTransferProtocol was extended to include the checksum type in the blockChecksum() response. DFSClient uses it in getFileChecksum() to determin the checksum type. Also append() can be configured to use the existing checksum type instead of the configured one. -- This message is automatically generated by JIRA.
