Sorry for landing very late here.
I think {{GlobalStorageStatistics.INSTANCE.reset()}} would be enough.it also
handles synchonization on {{GlobalStorageStatistics.INSTANCE}}.
*FileSystem#clearStatistics()*
{code}
3622final Iterator iterator =
3623GlobalStorageStatistics.INSTANCE.iterator();
3624while (iterator.hasNext()) {
3625 final StorageStatistics statistics = iterator.next();
3626 statistics.reset();
{code}
As during this time, if any other stats is getting inserted, then
ConcurrentModificationException can occur.
[~liuml07],[~jnp] If you agree,we can handle in separate jira.??

Steve Loughran commented on HADOOP-13283:
-
for the tests i was doing, i was just thinking of having a "snapshot" operation
which took the enum, built a list of the "before" Values, could do the same
with the next set, and so let me compare them. That's where I'm doing explicit
diffs of state (see {{S3ATestUtils.MetricDiff for the feature on a single
metric, with integrated assertions}}...I think production code might prefer the
reset, just to avoid having to keep the original metric snapshot around

Mingliang Liu commented on HADOOP-13283:
Thanks, [~ste...@apache.org]. I also believe reset is preferred for production
code use case. When I discuss this with [~hitesh], I think from Tez's point of
view, the reset operation is good enough by now (correct me if I'm wrong
[~hitesh]). However, I do believe snapshot is a nice-to-have feature,
especially for testing/debugging cases. As it's non-trivial (to me) to take
care of the memory overhead and consistency, and basically it needs a different
implementation, I think we can address this in separate JIRAs later.

Please check for stats null, particularly in UnionStorageStatistics. In case of
null stats, reset should be no-op I think.

Any reason why FileSystem.clearStatistics() is not being changed to call a
reset on GlobalStorageStats?

Thanks [~hitesh] for your comment. I think you point is very valid. The v2
patch will address this, along with unit tests.
I'll revise the NPE problem as well. Thanks, [~jnp].
