Chesnay Schepler closed FLINK-3998.
-----------------------------------
Resolution: Not A Problem
Exceptions caused by missing synchronization are catched, and the reporting
delayed to the next round.
This case can only occur on startup/teardown of the job/task/operator. During
this period, synchronization may produce additional overhead that should be
avoided.
> Access to gauges and counters in StatsDReporter#report() is not properly
> synchronized
