Description

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
