> 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:
> {quote}
> Error: java.lang.ClassNotFoundException: com.google.common.collect.ImmutableSet
> 	at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
> 	at java.security.AccessController.doPrivileged(Native Method)

> 	at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
> 	at org.apache.hadoop.hbase.ipc.SecureServer.<clinit>(SecureServer.java:96)
> {quote}
> We just need to add the dependency on the guava classes in the mapreduce.TableMapReduceUtil class.
