Todd Lipcon updated HDFS-2130: ------------------------------ Attachment: hdfs-2130.txt Fix for the findbugs warning. There was a needless null check on {{streams}} in {{BlockReceiver}}. Both of the implementations for {{createStreams}} always either return a non-null object or throw an exception. > Switch default checksum to CRC32C > --------------------------------- > > Key: HDFS-2130 > URL: https://issues.apache.org/jira/browse/HDFS-2130 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs client > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Attachments: hdfs-2130.txt, hdfs-2130.txt, hdfs-2130.txt > > > Once the other subtasks/parts of HDFS-2080 are complete, CRC32C will be a > much more efficient checksum algorithm than CRC32. Hence we should change the > default checksum to CRC32C. > However, in order to continue to support append against blocks created with > the old checksum, we will need to implement some kind of handshaking in the > write pipeline. -- This message is automatically generated by JIRA.
