I am having a problem using Spark H2O/H2O nodes: Predictor(Autoencoder) and Predictor(Dimension Reduction). I have warnings regarding to the MOJO category which must be DimReduction or AutoEncoder. I uploaded the modified workflow example: “kn_example_h2o_sparkling_water.knwf” from the site. The same problem is when I am using H2O k-Means node instead of H2O Random Forest Learner node.
And I have another question: how can I activate the Sparkling Water Flow UI? I tried to set the “spark.ext.h2o.node.enable.web” key TRUE for the Create H2O Sparkling Water Context node on another workflow on a Linux OS and I have this error: “\n\nERROR MESSAGE:\n\nResource/flow/index.html not found\n\n”. I uploaded the image with this error.
