-------------------------------
bq. This was turned on in the 20 originally and then we had to turn it off due
bugs.
The "bugs" were fixed a good while ago.
bq. Can you please explain the reason the make this change?
+ HBase needs it.
+ Its broken that users have to flip a configuration flag, then stop+start, to
make a basic fs api method work.

> 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
