> When running Giraph with more than one worker, ZooKeeper usually throws a
> bunch of 'lost reservation' info log messages for input splits at the end of
> the computation in workers' log. This clutters log file of workers, specially
> in cases where the job is running on a large graph with fairly large number
> of input splits.
> Here are examples of these log messages:
