MRS – new version and support of c4/m4 flavor

04/03/2020

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.
