------------------------------------

             Summary: Erroneous scheduling of co-located tasks
                 Key: FLINK-2225
                 URL: https://issues.apache.org/jira/browse/FLINK-2225
             Project: Flink
          Issue Type: Bug
            Reporter: Till Rohrmann
            Priority: Blocker


While running the {{ConnectedComponents}} example on a testing cluster, I encountered spurious failures of the job execution. The error was that the scheduler could sometimes not schedule co-located tasks because it did not find any suitable slots for deployment.

This error might be related to FLINK-1952 where a similar error was observed. The error might have been reintroduced by FLINK-2183 which fixed another scheduling error.
