Devaraj Das commented on HBASE-7851:
------------------------------------
Just a note that the guava dependency was already there in the
mapred.TableMapReduceUtil class. This patch just makes the
mapreduce.TableMapReduceUtil be in sync with that. I guess if we decide to
remove the guava dependency, we should do the same in both places..

> 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:
