MapReduce Service (MRS) now offers new versions of the most common open source distributions based on the current c4 and m4 flavors.
These new software versions are available:
- MRS 1.9.2 is based on Hadoop 2 and available with several components
- MRS 2.1.0 includes Hadoop 3 and can work up to 30% faster than Hadoop 2
Compatibility with Hadoop 2
- Users who are still working with Hadoop 2 can use the updated version 1.9.2 because the major update of Hadoop 3 doesn’t preserve full API level compatibility.
