Lars Hofhansl commented on HDFS-3721: ------------------------------------- Oh this is a 2.1.x vs 2.0.x issue...? The HDFS-744 patch is smaller than this patch, could we port that to 2.0.x? > 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 > Attachments: hdfs-3721.txt > > > 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 read or write data on the old cluster. -- This message is automatically generated by JIRA.
