For Apache Solr 7.x or older yes - Apache Hadoop 2.x was the dependency. Apache Solr 8.0+ has Hadoop 3 compatibility with SOLR-9515. I did some testing to make sure that Solr 8.0 worked on Hadoop 2 as well as Hadoop 3, but the libraries are Hadoop 3.
The reference guide for 8.0+ hasn't been released yet, but also don't think it was updated.
