Tests involving Hadoop/Accumulo do not work on Windows

[GCHQDeveloper314]

While looking at #2591 it was discovered that tests involving Hadoop/Accumulo do not work on Windows.

For Hadoop "Native IO is mandatory on Windows and without it you will not be able to get your installation working" (from Hadoop Wiki). This involves installing Hadoop libraries, setting the HADOOP_HOME environment variable and compiling and installing Native IO for windows. The Hadoop Native IO libraries for Windows are not distributed by Apache and must either be built from source or downloaded from a 3rd party.

Due to the above situation with Hadoop, all modules which have a test dependency on Hadoop fail to run tests on Windows. This includes at least hdfs-library,accumulo-store,accumulo-rest(plus most other rest modules), flink-library and all spark modules.

In addition there is what could be a separate problem with flink and JUnit where a temp directory cannot be deleted.

There's also a potential path problem with path path processing in common-rest which may just be linked to Hadoop:
