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

             Summary: Hadoop: IgniteHadoopIgfsSecondaryFileSystem must use HadoopClassLoader.
                 Key: IGNITE-3940
                 URL: https://issues.apache.org/jira/browse/IGNITE-3940
             Project: Ignite
          Issue Type: Sub-task
          Components: hadoop
    Affects Versions: 1.7
            Reporter: Vladimir Ozerov
             Fix For: 1.8


In new arhitecture {{IgniteHadoopIgfsSecondaryFileSystem}} should load dependent classes using {{HadoopClassLoader}}. We need to guarantee it.

Proposed solution:
1) Separate {{HadoopClassLoader}} is initialized for the file system on start ({{ctor}} or {{start}} method);
2) All interfaces methods are wrapped into {{HadoopUtils.setContextClassLoader}}
3) start/stop methods are wrapped as well.
