----------------------------------
Fix Version/s: (was: 0.12.0)
1.0.0
> 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
> Assignee: Andrew Palumbo
> Fix For: 1.0.0
>
>
> When one follows the instructions located in [README.md for H2O
> module|https://github.com/apache/mahout/blob/master/h2o/README.md] and tries
> to run tests in the distributed mode, tests run only in the local mode. There
> are three steps in the instruction:
> # {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 a different cloud name (or _masterURL_
> in terms of the code). If you look in the code, you can find the following:
> {code:title=DistributedH2OSuite.scala}
> ...
> mahoutCtx = mahoutH2OContext("mah2out" + System.currentTimeMillis())
> ...
> {code}
> After we removed the code which appends current time to cloud name, it
> started to work.
