Former user commented: Which dataset is this? I don't see this in smalldata or bigdata in H2O public test data folder.

Former user commented: I think this is related to PUBDEV-349, since it looks like the NA's are being parsed into Strings.

Former user commented: I'm unable to reproduce this error. I don't know what input parameters you used to build the GBM model, I used TARGET_B as my response and kept everything as default, the model build and prediction (on training set) work perfectly.
