Todd Lipcon created HDFS-3721: --------------------------------- Summary: hsync support broke wire compatibility Key: HDFS-3721 URL: https://issues.apache.org/jira/browse/HDFS-3721 Project: Hadoop HDFS Issue Type: Bug Components: data-node, hdfs client Affects Versions: 2.1.0-alpha Reporter: Todd Lipcon Assignee: Todd Lipcon Priority: Critical
HDFS-744 added support for hsync to the data transfer wire protocol. However, it actually broke wire compatibility: if the client has hsync support but the server does not, the client cannot write to the old cluster. -- This message is automatically generated by JIRA.
