             Summary: Hadoop MapReduce task fails after the prefered ispn server stopped 
                 Key: ISPN-6086
                 URL: https://issues.jboss.org/browse/ISPN-6086
             Project: Infinispan
          Issue Type: Bug
          Components: Hadoop Integration
            Reporter: Anna Manukyan
         Attachments: FailoverTest_when_prefered_stopped.log

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.
