      Description

      It doesn't seem that Yarn components, for example the ResourceManager or NodeManager, do build/package version checking before trying to communicate with each other.

      The objective of this ticket is to support the following requirements / use cases:

      • New versions can be marked incompatible with old versions, and services should be prevented from communicating with each other in such case. This will avoid non-deterministic behavior/problems resulting from incompatible components trying to communicate with each other.
      • Permitting a policy for running different - but compatible - versions on the same cluster (for example, in a rolling upgrade scenario). See HDFS-2983 for the corresponding HDFS implementation.
