I'm stuck at step 2 of the H2O generated POJO model WebApp Example at https://github.com/h2oai/app-titanic .
Step 2 is about using H2O in R see http://h2o-release.s3.amazonaws.com/h2o/rel-slater/1/index.html#R .
In the R interactive command-line I get the following error:
===============================================================
> localH2O = h2o.init()
Successfully connected to http://127.0.0.1:54321/
ERROR: Unexpected HTTP Status code: 412 Precondition Failed (url = http://127.0.0.1:54321/3/Cloud?skip_ticks=true)
Error: lexical error: invalid char in json text.

Googling for answers turned up this one http://stackoverflow.com/questions/27558048/rga-package-lexical-error but does not do any help.
Hoping someone there has a solution or can help figure out what to do.
Best regards,
Carlos
By the way, I am using Ubuntu 14.04.3 LTS, with R version 3.2.1 RC (2015-06-10 r68509)
Best regards,
Carlos
Would it matter if the machine is an instance of Ubuntu in AWS?
