Description:
As of now during cancellation process reduce's node send cancellation requests
to map nodes and don't wait answer from them. See usage of
org.apache.ignite.internal.processors.query.GridQueryCancel#set, where set
action on cancellation. There are two main usage in GridReduceQueryExecutor,
and action is send GridQueryCancelRequest with request id to set of nodes.
Need to await answer from all of map nodes.
Proposed solution is:
All nodes consuming GridQueryCancelRequest should await real cancellation of
map part of query and send back new message with cancellation confirmation.
Reduce node ( which send GridQueryCancelRequest to all map nodes)
was:As of now during cancellation process reduce's node send cancellation
