unable to convert using as.h2o after updating macbook
dhil...@googlemail.com
Earlier i was able to do all things using h2o RStudio, After updating macbook to OS X El Capitan 10.11.5 & re-installing java, i am getting error while converting R object to h2o object using
library(h2o)
localH2O <- h2o.init(nthreads = -1)
h2o.init()
trainM.h2o <- as.h2o(trainModel)
Below error on last command
ERROR: Unexpected HTTP Status code: 500 Server Error (url = http://localhost:54321/3/PostFile?destination_frame=%2Fprivate%2Fvar%2Ffolders%2Fcj%2Fz9hjhlgs0vxbmxv2khxl_7680000gp%2FT%2FRtmpkCwgtt%2Ffile729381d82a7.csv_sid_8233_14)

I have tried as mentioned below by some of the user to try as below, which gives me same error pasted below commands.
library(h2o)
h2o.init()
irisPath = system.file("extdata", "iris.csv", package="h2o")
iris_data <- h2o.uploadFile(irisPath, destination_frame = "",parse = T,header = T, sep = ",", na.strings = c("unknown"),progressBar = FALSE, parse_type = "CSV")

hi, can you try this:
1. start over
2. call h2o.startLogging()
this will print the name of a log file.
3. try your failing sequence again.
4. look at the log file created by startLogging.
thanks,
tom

ok, and now what does the actual h2o log file itself say?
not what shows up in the R window, but the log file.
if you are starting h2o from within R, you will see the path of the stdout and stderr log files printed when the h2o process is started.
