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

             Summary: Hadoop: print warning if Hadoop is found in classpath of parent classloader.
                 Key: IGNITE-3928
                 URL: https://issues.apache.org/jira/browse/IGNITE-3928
             Project: Ignite
          Issue Type: Sub-task
          Components: hadoop
    Affects Versions: 1.7
            Reporter: Vladimir Ozerov
            Assignee: Ivan Veselovsky
             Fix For: 1.8


Normally parent classloader should not have Hadoop in classpath. Otherwise we may end up in
JAR hell situation.

We need to probe parent classloader for Hadoop and print a warning if Hadoop is likely to
be in the classpath. E.g. we can probe for {{FileSystem}} or {{Configuration}} class.
