Daryn Sharp commented on MAPREDUCE-4762:
----------------------------------------
Be very careful because I seem to remember a problem caused by the tests
registering the custom token renewer. The believe the test jar is by default
in the CLASSPATH, so deploys will load the custom renewer and cause problems.

> Key: MAPREDUCE-4762
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4762
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Ivan A. Veselovsky
>
> 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.
