Mingliang Liu commented on HADOOP-14472:
I'd suggest we currently remove this assertion. This fails 8 out of 10 runs on
my laptop (not Azure VM).
A better approach is to support metrics or instrumentation, and we can verify
that to make sure hsync was called enough times. As S3A.

Steve Loughran commented on HADOOP-14472:
-
Looks pretty brittle: it's trying to verify that hsync() flushed by asserting
the operation time is > a min value
{code}
// A true, round-trip synchronous flush to Azure must take
// a significant amount of time or we are not syncing to storage
correctly.
{code}
