[jira] Resolved: (HBASE-3264) Remove unnecessary Guava Dependency

     [ https://issues.apache.org/jira/browse/HBASE-3264?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-3264.
--------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 0.90.1)
                   0.90.0
     Hadoop Flags: [Reviewed]

Committed.

I agree we should use libs instead of writing the stuff ourselves but also that we move to minimize dependencies.  In this case, I like the bit of Nicolas footwork that changes a little bit of code so we can cut our client dependencies by 25 (or 33?) percent.

> Currently, TableMapReduceUtil uses Guava for trivial functionality and addDependencyJars() currently adds Guava by default.  However, this jar is only necessary for the ImportTsv MR job.  This is annoying when naively bundling hbase jar with a MR job because you now need a second dependency jar.  Should default bundle with only critical dependencies and have jobs that need fancy Guava functionality explicitly include them.
