As descriibed in HADOOP-6313, the real expected semantics should be "flushes out to all replicas and all replicas have done posix fsync equivalent - ie the OS has flushed it to the disk device (but the disk may have it in its cache)." This jira aims to implement the expected behaviour. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
