The Apache group has given approval for the release of Apache Hadoop 2.3.0. It is available for download at your favorite mirror. It includes:
- Support for Heterogeneous Storage hierarchy in HDFS.
- In-memory cache for HDFS data with centralized administration and management.
- Simplified distribution of MapReduce binaries via HDFS in YARN Distributed Cache.
…along with the expected bug fixes. One particularly visual difference is in the Name Node web UI. It has been improved to be more visually appealing.
If you have been following my instructions to set up your own cluster, not to worry…I verified that they also work for this version.
