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

             Summary: FileSwapSpaceSpi iterator does not support remove operations
                 Key: IGNITE-1156
                 URL: https://issues.apache.org/jira/browse/IGNITE-1156
             Project: Ignite
          Issue Type: Bug
            Reporter: Yakov Zhdanov
            Priority: Minor


This makes impossible to undeploy from swap.

See {{org.apache.ignite.internal.processors.cache.GridCacheSwapSelfTest#testSwapDeployment}}

Although swap cannot be cleared (undeployed entries cannot be removed) test passes, since swapped entry cannot be moved back to heap and exception is output.

Proper fix would be to support iterator remove operation properly.
