---------------------------------------
Summary: Hadoop: Fix native libraries loading mechanism.
Key: IGNITE-3929
URL: https://issues.apache.org/jira/browse/IGNITE-3929
Project: Ignite
Issue Type: Sub-task
Components: hadoop
Affects Versions: 1.7
Reporter: Vladimir Ozerov
Assignee: Ivan Veselovsky
Fix For: 1.8
Currently we do the following to load native libraries:
1) Ask parent class loader (normally it is app class loader) to load
{{org.apache.hadoop.util.NativeCodeLoader}} class. It will force loading of
relevant Hadoop native libraries.
2) Then hack into parent class loader internals, find loaded library, and wire
it up to current classloader.
This approach will not work any more because parent classloader normally will
not have Hadoop in classpath.
We should provide alternative solution. One idea is to hack into
{{findLibrary}} method: when it is called we can create alternative library
name and point it, e.g., to symlink of a target library.
