hc.as_h2o_frame() (from Sparkling Water 2.3.19, connected to h2o external backend cluster).
Same code worked fine before upgrade (from SW 2.3.13).
See full exception here -
thanks for reporting. I'm still unable to reproduce, even though it's just NPE.
Having a full YARN logs of the external H2O cluster would help us a lot.
Was able to reproduce, will work on a fix soon
Is there is a workaround for this issue? Otherwise we will have to downgrade.
I was just able to repro at this stage, not sure about workaround. For now, please downgrade
Fix is done, will be in the next release
