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

             Summary: Make ignite-shmem lib optional
                 Key: IGNITE-4152
                 URL: https://issues.apache.org/jira/browse/IGNITE-4152
             Project: Ignite
          Issue Type: Bug
            Reporter: Denis Magda
             Fix For: 1.8


Presently, if someone starts up a cluster and has at least two nodes running on a single Unix
machine then those nodes will be communicating over the shared memory (shmem) by default.

This approach sounds absolutely reasonable but the shmem library is not ideal at the moment.
There are many situations when a cluster may hang in the production or during long running
tests due to some unclear issues in shmem internals. Even from Ignite community side we have
the following shmem related issues
