Hi,
When I build cubes with /derived columns/ always get the same error at
"Build Dimension Dictionary" step.
kylin version: 1.5.3
error:
java.lang.NullPointerException

The curious thing is that I don't use any Date column, so it is pretty
baffling. And only happens with cubes using derived columns.
Any idea will be helpful,
Thanks
