> As we reduce the default retries number to 10 and now the default start log
> errors counter is 9. So it only log the error at the last retry. So we should
> reduce the default hbase.client.start.log.errors.counter, too.

> * heuristic for the number of errors we don't log. 9 was chosen because we
> wait for 1s at
