Denis Magda updated IGNITE-4152: -------------------------------- Description: 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 https://issues.apache.org/jira/browse/IGNITE-1578 https://issues.apache.org/jira/browse/IGNITE-1294 Let's make the shmem lib optional by putting it into "{{ignite-release/libs/optional}}" folder and removing any explicit reference we may have in a pom.xml file. was: 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.
