> I have added tests to the infinispan-hadoop testsuite testing the load balancing of mapreduce task in case if the input server which is specified as a parameter to Hadoop configuration is stopped. 
> The test is performed on 4 node cluster. The data read is performed from Infinispan cache, the write is performed to HDFS. 
> There are 200000 entries in the cache. As soon as the Hadoop Job is submitted for performing map/reduce task, the preferred server is stopped. 
> As a result, the Hadoop Map/Reduce result map is empty.
> You can find the test execution log attached.
