<p>Each integration that we support incurs a cost for testing and maintenance as new
features are added in ES-Hadoop. We’ve seen the usage statistics dropping for the
Cascading integration over the last couple of years. These include download numbers,
community posts, and open issues. Additionally, ES-Hadoop only supports the
Cascading 2 line. Cascading is already into it’s 3.X line and we haven’t seen much
interest or pressure to get on to any of the newer versions. Due to these factors,
Cascading was deprecated in the 6.6 release, and has been removed in the 7.0.0
release.</p>

<p>ES-Hadoop 7.0.0 and above requires a minimum Java version of 1.8 or above. The library
will no longer be compiled for Java 1.6 or Java 1.7.</p>
