Hi Bart, With the diagnosis pack, the problem is much clearer.
- Seems you are using a CDH quickstart sandbox which is very limited in resource. In that case, it is expected that running 2 or 3 table stats at the same time could hang due to resource competition (thus deadlock) in YARN. The same thing happens in my HDP sandbox btw. - Also the cube Ksiegarski_cube contains 30 dimensions, which is challenging even for some Kylin expert. Suggest start with a simpler cube with 20 dimensions or less. And use hierarchy / joint / mandatory more heavily to control the overall cuboid number.
