LGTM, though the doc reference to HDFS should be relative to the final build 
paths, i.e. self-contained.

Still need a story for viewfs

Thanks [~hexiaoqiao]! IMO the preconditions section should be specific to what 
conditions should be met prior to calling the method, and we should move the 
sentence:
{quote}
It is currently only implemented for HDFS and others will just throw 
UnsupportedOperationException.
{quote}
to the previous section before preconditions (also following other methods such 
as concat).

I agree with [~hexiaoqiao] and think we can mention that this is currently only 
implemented for HDFS and others will just throw 
{{UnsupportedOperationException}}, similar to what we're doing for {{concat}}, 
{{truncate}} etc. 

Otherwise I'm +1 on this. Thanks.

Thanks [~shv] for your update. just wonder if we need note Preconditions that 
it will throw UnsupportedOperationException if backend FileSystem not implement 
msync interface. +1 once update.
More, target version also include branch-3.2 right? If that, will wait to 
resolve. 
cc [~ste...@apache.org] would you mind have another checks to push this forward?

Konstantin Shvachko commented on HDFS-15751:


Added documentation for {{msync()}}.
I put a reference to HDFS documentation describing [Consistent Reads from 
Observer|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/ObserverNameNode.html]
 particulalrly the semantics of {{msync()}} in HDFS. Otherwise it is hard to 
define it in abstract terms without the context.

I was also thinking about {{AbstractContract}}* type tests for {{msync}} but 
could not think of anything valuable that can be tested here. Essentially we 
need call {{mkdir()}} and then verify that after {{msync}} the metadata exists 
via a read call, which we do for HDFS in {{TestConsistentReadsObserver}}. But 
it is a probabilistic thing as it can succeed even without synchronization if 
standby catches up fast enough. I guess testing consistency contracts is 
similar to atomicity, which we don't test in {{AbstractContract}} tests, since 
it not clear how.
