Dmitry Yaraev updated MAHOUT-1767:
----------------------------------
    Description: 
When one follows the instructions located [README.md for H2O module|https://github.com/apache/mahout/tree/master/h2o], test run in the local mode. There are three steps:

# {code}
host-1:~/mahout$ ./bin/mahout h2o-node
...
.. INFO: Cloud of size 1 formed [/W.X.Y.Z:54321]
{code}
# {code}
host-2:~/mahout$ ./bin/mahout h2o-node
...
.. INFO: Cloud of size 2 formed [/A.B.C.D:54322]
{code}
# {code}
host-N:~/mahout/h2o$ mvn test
...
.. INFO: Cloud of size 3 formed [/E.F.G.H:54323]
...
All tests passed.
...
host-N:~/mahout/h2o$
{code}

First two steps are for executing worker nodes. The last one is for executing tests. According to the instruction, after launching tests one more worker is started. And it should join to the same cloud which other worker nodes forms. But it does joined them because it has different cloud name (or _masterURL_ in terms of the code). If you look in to the code, you can found the following:
{code:title=DistributedH2OSuite.scala}
...
mahoutCtx = mahoutH2OContext("mah2out" + System.currentTimeMillis())
...
{code}

We tried to remove generated suffix from the cloud name. After that it started to work.
