Description

We increment the count before using the backoff policy. So if there are any policy splits the requests, the total increment will be smaller than total decrement.

AsyncProcess.java

private void sendMultiAction(...) {
  ...
  incTaskCounters(multiAction.getRegions(), server);
  Collection<? extends Runnable> runnables = getNewMultiActionRunnable(server, multiAction, numAttempt);
  ...
}
