stack commented on HBASE-7851:
------------------------------
Here is the issue where we stripped back guava: HBASE-3264 Sounds like it was
not comprehensive enough stripping (i.e. missed security). The notion that we
minimize MR dependencies and that we try to strip guava because its not
heavily used comes through in the issue.
> Include the guava classes as a dependency for jobs using
> mapreduce.TableMapReduceUtil

> The guava classes go as a dependency for jobs using TableMapReduceUtil from
> the org.apache.hadoop.hbase.mapred package but the same doesn't happen for
> jobs using the same class from org.apache.hadoop.hbase.mapreduce package. Due
> to this, tasks of the mapreduce jobs that wants to communicate with a secure
> cluster fails. The stack trace of the failing tasks:
