java.lang.NoSuchMethodError since openjdk 1.8.0_252
Since openjdk version 1.8.0_252 we are unable to launch an H2O cluster on EMR due to the following error (happens when we call h2o_context(sc) from R):
This works fine on one of our older clusters, where openjdk version is 1.8.0_242.
H2O build version: 126.96.36.199 (yu)
Sparkling Water version: 188.8.131.52-1-2.4

Thank you! Would it be possible to share the snipper were you configure your algorithm?
Also CC: and
We are using AUCPR with cross-validation and early stopping for tuning the number of trees for XGBoost. At some point, the interpolation of AUCPR got updated (was linear initially). However, after that change we’re seeing convergence way later (e.g. 2k trees instead of 500 trees). Furthermore – we did shadow mode testing on live data and noticed that models trained with the “old” way of calculating AUCPR actually perform way better. This also had implications on training speed (needed roughly 4x more time).
Thank you for your reply! Could you please share what kind of issue are you having on the latest version? Maybe we can help with that.
