I am having trouble running h2o from within R. Just installed following R instructions on this page: <http://h2o-release.s3.amazonaws.com/h2o/rel-wolpert/2/index.html>. Then, 

```
library(h2o)
h2o.init(nthreads = -1, max_mem_size = '2g', ip = "127.0.0.1") 

```

h2o server wouldn't start:

```
    H2O is not running yet, starting it now...

Note:  In case of errors look at the following log files:
    /var/folders/7y/p9rdbryd5zg5nvtjgdzyshx40000gt/T//RtmpvbbPTR/h2o_arman_started_from_r.out
    /var/folders/7y/p9rdbryd5zg5nvtjgdzyshx40000gt/T//RtmpvbbPTR/h2o_arman_started_from_r.err

```

On the other hand, I can run the server from the terminal

```
java -jar /Users/arman/Library/R/3.4/library/h2o/java/h2o.jar
# Retrieved the location of jar file in R using  h2o:::.h2o.downloadJar()

```

The above command works. I can continue running from terminal, but h2o.init provides many convenience options as well as code consistency. 

Any ideas why h2o fails to initialize from R? Also, tried from Python and had the same problem.
