Ivan Veselovsky created IGNITE-1326:
---------------------------------------

             Summary: IGFS: data write errors should be failed over in the level of IGFS output
stream implementation.
                 Key: IGNITE-1326
                 URL: https://issues.apache.org/jira/browse/IGNITE-1326
             Project: Ignite
          Issue Type: Bug
            Reporter: Ivan Veselovsky
            Assignee: Ivan Veselovsky


See org.apache.ignite.internal.processors.igfs.IgfsDataManager.WriteCompletionFuture#onError
: currently if a node failed to receive data block, this implementation completes the write
future with an Exception, so output stream method will throw exception. 
Preferably we should do failover there , recalculate blocks affinity on the new topology and
re-send the block(s) again.
We can also just use the cache .put() functionality (manual sending of the file blocks was
implemented due to performance optimization, as far I know).
