I looked around for people in a similar situation and this post seems to sum up what you're seeing pretty well: https://community.cloudera.com/t5/Advanced-Analytics-Apache-Spark/java-lang-IllegalArgumentException-java-net-UnknownHostException/td-p/12874

Notice that in the line that says Tokenizing documents in hdfs://user/hduser/seqoutputdata the first thing after the hdfs:// is user.

That user is being interpreted as a hostname in that path, which is why the java.net.UnknownHostException thinks it's looking for a host called user.

Looks like you may be able to include a valid hostname in any path you're passing to Mahout: e.g., hdfs://host/user/hduser/seqoutputdata.
