Oh, I think I found the problem. Based on the stack trace, InputBootstrapper is being loaded along with the Hadoop Configuration object (org.apache.hadoop.conf.Configuration), which I found in my class path in hadoop-3.2.2/share/hadoop/client/hadoop-client-api-3.2.2.jar (and verified by unpacking the jar and running javap on the Configuration class to see the reference to InputBootstrapper).
However, I also ran the following and saw that class appear in two different jars for Hadoop: for x in $(find hadoop-3.2.2/ -name '*.jar'); do jar tf "$x" | grep hadoop.conf.Configuration.class && echo "$x"; done org/apache/hadoop/conf/Configuration.class hadoop-3.2.2/share/hadoop/common/hadoop-common-3.2.2.jar org/apache/hadoop/conf/Configuration.class hadoop-3.2.2/share/hadoop/client/hadoop-client-api-3.2.2.jar After inspecting hadoop-3.2.2/share/hadoop/common/hadoop-common-3.2.2.jar, I can confirm that the Configuration.class that is contained in that has references to the non-shaded version of InputBootstrapper. So, it seems like all you need to do is ensure that your jar containing the shaded version is higher on your class path than the one containing the reference to the non-shaded version. So, put hadoop-3.2.2/share/hadoop/client/hadoop-client-api-3.2.2.jar higher on your class path than hadoop-3.2.2/share/hadoop/common/hadoop-common-3.2.2.jar Alternatively, you could track down the upstream jar for the wstx dependency and place that on your class path, but that's probably more trouble than the first option. Hope that helps!
