Shows the Hadoop RPC protocol version and compatible data-fabric client versions for each release.
Each core release version is associated with a Hadoop RPC protocol version. The JobTrackers or ResourceManagers in a given cluster accept only the jobs submitted from clients with a compatible protocol version.

1Release 6.2.0.5 and later.
2MapReduce version 1 and version 2 use the same protocol version.
3A 4.0.2 client can submit MRv2 jobs to a 4.1, 5.0, or 5.1 cluster configured with zero-configuration ResourceManager failover (RM HA) as long as the client is also configured with zero-configuration RM HA.
4If you want to submit MapReduce v2 jobs to a 4.0.x cluster configured with zero-configuration RMHA, you must use a 4.0.2 client on a 4.0.2 cluster.
