| * This class is an MR2 replacement for older MR1 MiniMRCluster, that was used |
| * by tests prior to MR2. This replacement class uses the new MiniMRYarnCluster |
| * in MR2 but provides the same old MR1 interface, so tests can be migrated from |
| * MR1 to MR2 with minimal changes. |
| * |
| * Due to major differences between MR1 and MR2, a number of methods are either |
| * unimplemented/unsupported or were re-implemented to provide wrappers around |
| * MR2 functionality. |
| * |
| * @deprecated Use {@link org.apache.hadoop.mapred.MiniMRClientClusterFactory} |
