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.
