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

             Summary: Hadoop: better defaults to memory page size and message size.
                 Key: IGNITE-4469
                 URL: https://issues.apache.org/jira/browse/IGNITE-4469
             Project: Ignite
          Issue Type: Task
          Components: hadoop
    Affects Versions: 1.8
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
            Priority: Minor
             Fix For: 2.0


Currently we have too low shuffle message size and too low initial memory buffer size - 128Kb
and 32Kb respectively. 

As we target big data use case, it makes sense to make these properties bigger. According
to several experiments, good size is 1Mb each.
