> Key: MAPREDUCE-4762
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4762

>
> 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.
