-------------------------------------
Summary: Unable to run tests on H2O enigne in distributed mode
Key: MAHOUT-1767
URL: https://issues.apache.org/jira/browse/MAHOUT-1767
Project: Mahout
Issue Type: Bug
Components: Documentation
Affects Versions: 0.11.0
Reporter: Dmitry Yaraev
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 mode worker is
started. And it should join to the same cloud as other worked 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.
