> When distributed log splitting is enabled then it is better to call
> splitLog() for all region servers simultaneously. A large number of splitlog
> tasks will get scheduled - one for each log file. But a splitlog-worker
> (region server) executes only one task at a time and there shouldn't be a
> danger of DFS overload. Scheduling all the tasks at once ensures maximum
> parallelism.
