> The test org.apache.hadoop.mapreduce.security.token.TestDelegationTokenRenewal is @Ignor-ed. 
> Due to that several classes in package org.apache.hadoop.mapreduce.security.token have zero unit-test coverage.
> The problem is that the test assumed that class org.apache.hadoop.mapreduce.security.token.TestDelegationTokenRenewal.Renewer is used as a custom implementation of the org.apache.hadoop.security.token.TokenRenewer service, but that did not happen, because this custom service implementation was not registered. 
> We solved this problem by using special classloader that is invoked to find the resource META-INF/services/org.apache.hadoop.security.token.TokenRenewer , and supplies some custom content for it. This way the custom service implementation gets instantiated.
