             Summary: BspServiceMaster finishes ZooKeeper cleanup without getting all workers
to complete
                 Key: GIRAPH-747
                 URL: https://issues.apache.org/jira/browse/GIRAPH-747
             Project: Giraph
          Issue Type: Bug
          Components: bsp
    Affects Versions: 1.0.0
            Reporter: Chuan Lei
            Assignee: Chuan Lei
             Fix For: 1.0.0


In BspServiceMaster, the function cleanUpZooKeeper should wait for the number of workers and
masters to complete. However, it appears that maxTasks only takes workers into consideration.
Consequently, the worker straggler may fail to report to the ZooKeeper due to the path gets
removed too early. This will cause No lease on path File does not exist exception at runtime.
