----------------------------------------------------------------

The tests that check file's owner on Ignite-client based mode are failed due to current user
isn't passed to client tasks.
Tests:
{code}
IgniteHadoopFileSystemClientBasedDualAsyncSelfTest.testOpen
IgniteHadoopFileSystemClientBasedDualAsyncSelfTest.testMkdirs
IgniteHadoopFileSystemClientBasedDualAsyncSelfTest.testSetOwner
IgniteHadoopFileSystemClientBasedDualSyncSelfTest.testOpen
IgniteHadoopFileSystemClientBasedDualSyncSelfTest.testMkdirs
IgniteHadoopFileSystemClientBasedDualSyncSelfTest.testSetOwner
{code}

> IGFS client (IgniteHadoopFileSystem) communicates IGFS over endpoint - either TCP or
shmem.
> Only single endpoint can be specified. As such, should the server went down, IgntieHadoopFileSystem
(either new or existing) is no longer operational. 
> We need to let user specify several endpoints and failover/balance between them.
> Look at Hadoop HA first to get an ideas on how to configure multiple addresses.
