> Many dependent projects like HBase, Hive, Pig, etc, depend on MiniMRCluster
> for writing tests. Many users do as well. MiniMRCluster, however, exposes MR
> implementation details like the existence of TaskTrackers, JobTrackers, etc,
> since it was used by MR1 for testing the server implementations as well.
> This JIRA is to create a new interface which could be implemented either by
> MR1 or MR2 that exposes only the client-side portions of the MR framework.
> Ideally it would be "recompile-compatible" with MiniMRCluster for most
> applications, and the MR1 implementation could be backported to 20x branch.
> Thus, dependent projects like HBase could migrate to this implementation and
> test against both MR1 and MR2. We can also use this to port over the current
> functional tests that use only the client-side features of MiniMRCluster.
