> Key: IGNITE-761
> URL: https://issues.apache.org/jira/browse/IGNITE-761
> Project: Ignite
> Issue Type: Task
> Components: hadoop
> Reporter: Ivan Veselovsky
> Assignee: Ivan Veselovsky
> Fix For: 1.6
>
>
> Spawned from https://issues.apache.org/jira/browse/IGNITE-218 :
> When a mapred task is working in Ignite node, it may access
> IgniteHadoopFileSystem, which, in turn, may have a secondary file system.
> Solving the issue 218 we tried to pass the user context of the mapred task
> using standard Hadoop mechanism ugi.doAs().
> But experiments show that this user context is not always correctly passed to
> the IgniteHadoopFileSystem constructor.
> Preliminary investigation shows that Principal list got from the Subject are
> empty. This happens because the principal list is got by class key, in case
> of Hadoop this is User.class. But if the caller class "User.class" is loaded
> by another classloader, that class is not identical to the class "User.class"
> that was used upon Principal creation, so the returned list is empty.
