following features.

New features compared to Hadoop-2.x 0.9.8 are:

    - Compliant with Apache Hadoop 2.7.1 and Hortonworks Data
      Platform (HDP) 2.3.0.0, and Cloudera Distribution including
      Apache Hadoop (CDH) 5.6.0 APIs and applications
    - Plugin for Cloudera Distribution Including Apache Hadoop (CDH)
      (tested with 5.6.0)
    - Automatic Locality-aware Shuffle in MapReduce

Bug Fixes (compared to Hadoop-2.x 0.9.8):

    - Fix an issue for running with Apache HBase 1.1.2
    - Fix an issue for running with multiple DataNode processes per node

The complete set of features for RDMA Apache Hadoop-2.x 0.9.9:

        - Enhanced hybrid HDFS design with in-memory and heterogeneous
          storage (HHH)
            - Supports three modes of operations
                - HHH (default) with I/O operations over RAM disk, SSD, and HDD
                - HHH-M (in-memory) with I/O operations in-memory
                - HHH-L (Lustre-integrated) with I/O operations in local
                  storage and Lustre
            - Policies to efficiently utilize heterogeneous storage
              devices (RAM Disk, SSD, HDD, and Lustre)
                - Greedy and Balanced policies support
                - Automatic policy selection based on available storage types
            - Hybrid replication (in-memory and persistent storage) for
              HHH default mode
            - Memory replication (in-memory only with lazy persistence) for
              HHH-M mode
            - Lustre-based fault-tolerance for HHH-L mode
                - No HDFS replication
                - Reduced local storage space usage
    - MapReduce over native InfiniBand and RoCE
        - RDMA-based shuffle
        - Pre-fetching and caching of map output
        - In-memory merge
        - Advanced optimization in overlapping
            - map, shuffle, and merge
            - shuffle, merge, and reduce
        - Optional disk-assisted shuffle
        - Automatic Locality-aware Shuffle
        - High performance design of MapReduce over Lustre
            - Supports two shuffle approaches
                - Lustre read based shuffle
                - RDMA based shuffle
            - Hybrid shuffle based on both shuffle approaches
                - Configurable distribution support
