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

             Summary: IGFS file cannot be removed when underlying HDFS file is removed externally.
                 Key: IGNITE-1407
                 URL: https://issues.apache.org/jira/browse/IGNITE-1407
             Project: Ignite
          Issue Type: Task
          Components: hadoop
    Affects Versions: 1.1.4
            Reporter: Vladimir Ozerov
             Fix For: ignite-1.5


In this case we simply check HDFS for file existence, it returns false, and we exit immediately without trying to remove a file from IGFS.
Current approach offers better performance, but require all mutable interaction with file system to happen through IGFS.
Looks like we have to give user ability to choose between two options:
1) Better performance, but all goes through IGFS;
2) Worse performance, but all external changes do not break IGFS.
