---------------------------------------
Summary: Throw sensible error from IgniteHadoopFileSystem if real
file system is not IgniteHadoopIgfsSecondaryFileSystem
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
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.
