> Key: IGNITE-2340
> URL: https://issues.apache.org/jira/browse/IGNITE-2340
> Project: Ignite
> Issue Type: Task
> Components: hadoop
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Labels: important
> Fix For: 1.6
>
>
> Consider the following scenario:
> 1) User configures some custom secondary file system;
> 2) Some paths are set to PROXY mode (e.g. default modes);
> 3) User instantiates IgniteHadoopFileSystem somewhere else.
> Result:
> IgniteHadoopFileSystem notices PROXY paths and tries to get FileSystem
> factory from handshake request, but it is null. As a result, NPE is thrown a
> moment later.
> Proposed fix:
> If factory is null. we must throw an exception and advise user to set
> IgniteHadoopIgfsSecondaryFileSystem as secondary file system.in IGFS
> configuration.
