Hi ,I run into some exception while Merge Cuboid Data.I set the auto merge thresholds to
7 days by default, the cube already have 8 segment,so it automatic start a merge job,then
fail with exception as follow:
===============

seems like it relate to dict,I do have some dimension with dict encoding:
[cid:_Foxmail.1@e8154662-2fdc-4074-b4bc-723745b0590b]
kylin 1.5.3

some of those segments maybe empty,other not,I think this could be the cause?
any idea?
