Liyin Tang commented on HDFS-744:
---------------------------------
Since we are now using new Create API to force sync, there is no need to enable
the syncOnClose any more. Single packet will not across block boundary.
> Support hsync in HDFS

> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Hairong Kuang

> HDFS-731 implements hsync by default as hflush. 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.
