-------------------------------------

Thanks for chiming in Suresh.

Wrt #1 see [this comment in HDFS-3120|https://issues.apache.org/jira/browse/HDFS-3120?focusedCommentId=13241903&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13241903]
that outlines the proposal that Todd, Nicholas and I thought was best. Feel free to file a
follow-on jira for an improvement.

Wrt #2 add a new option to disable durable sync? Personally I don't think we should HADOOP-8230

> Per HDFS-3120 for 1.x let's:
> - Always enable the sync path, which is currently only enabled if dfs.support.append
is set
> - Remove the dfs.support.append configuration option. We'll keep the code paths though
in case we ever fix append on branch-1, in which case we can add the config option back
