Folks, I finished development on IGNITE-4157 <https://issues.apache.org/jira/browse/IGNITE-4157> *Use discovery custom messages instead of marshaller cache.*
Latest CI build <http://ci.ignite.apache.org/viewLog.html?buildId=392762&tab=buildResultsDiv&buildTypeId=IgniteTests_RunAll> in team city looks very good, there are no tests failures related to my refactoring (only flaky tests are broken, this set varies from build to build) nor build hangs. I believe the code is stable enough and ready to be reviewed and merged to ignite-2.0 branch. Please take a look at pull request pull/1271 <https://github.com/apache/ignite/pull/1271>. Thanks, Sergey.
