> 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:
