             Summary: hadoop-auth module cannot import non-guava implementation in hatoop util
                 Key: HADOOP-17960
                 URL: https://issues.apache.org/jira/browse/HADOOP-17960
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Ahmed Hussein


hadoop-common  provides several util implementations in {{org.apache.hadoop.util.*}}. Since hadoop-common depends on hadoop-auth, all the utility implementations cannot be used within hadoop-auth.

There are several options:
* similar to {{hadoop-annotations}} generic and utility implementations such as maps, Strings, Preconditions, ..etc could be moved to a new common-util module that has no dependency on other modules.
* easier fix is to manually replace the guava calls in hadoop-auth module without importing {{hadoop.util.*}}. Only few calls need to be manually replaced: {{Splitter}}, {{Preconditions.checkNotNull}}, and {{Preconditions.checkArgument}}
