Description

The latest upgrade of the Hadoop dependency dates back to Dec 2017 (NUTCH-2354). We might upgrade to the latest version of Hadoop 2.x (2.9.2).

Note: Nutch 1.15 (or master) built with Hadoop 2.7.4 runs seamlessly on Hadoop 3.x. This should be also the case for 2.9.4 (to be tested), so we still might wait for the final upgrade to Hadoop 3.x to ensure backward-compatibility.
