---------------------------------------
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.
