[jira] [Created] (FLINK-1170) Localization of InputSplits is not working properly

Robert Metzger created FLINK-1170:
-------------------------------------

             Summary: Localization of InputSplits is not working properly
                 Key: FLINK-1170
                 URL: https://issues.apache.org/jira/browse/FLINK-1170
             Project: Flink
          Issue Type: Bug
          Components: Distributed Runtime
            Reporter: Robert Metzger
            Assignee: Robert Metzger


While running some benchmarks, I found that Flink is not properly assigning the InputSplits.

On my testing cluster, ALL splits were assigned to remote HDFS DataNodes, which causes a lot of network I/O.
