h2o version vs h2o R version conflict


Quite new to h2o. I updated my h2o-R package to 3.26 and I also installed the h2o cluster one by running

  • java -jar h2o.jar'

After running both and the h2o flow was accessible on the browser, when I run h2o.init(), it's still telling me that my h2o cluster is at 3.24 and h2o-R package is at 3.26.

Do I need to remove a previous h2o.jar version? How would I go about doing that?

I have forced it to work by initializing h2o by having the strict version check be false but, I want both h2o and h2o-R to be on the same version.

Thanks a lot!

P.S. I have attached screenshots of the errors.

Solution

  • The cluster information printed shows that it's connecting to an H2O cluster (version 3.24.0.5) that was started 30 minutes ago (running at the default location, localhost:54321). You will need to shut that one down first (kill the java process from the command line or simply, h2o.shutdown().

    You don't need to remove or uninstall anything, you just need to kill the active (old) cluster. After that, start from R using h2o.init() and it will use the updated version.
