Hey @pdmack as far as I can see, you're correct. javax.servlet:servlet-api
is not currently a dependency for most (?) Hadoop versions. It seems to come in
with versions of Hadoop 2.0.x via hadoop-hdfs. Excluding it should be fine
since it is not desirable where it is brought in, and not brought in elsewhere.
Just check that it all works, that the web UI starts. I have managed to
accidentally exclude all copies of the servlet API accidentally before!
