Hi All,

"Cardinality", who can help fix it? Thanks! The snapshot is as below:

Hi Na,
I have built this cube for many days already. But it still can’t show
“Cardinality” information. I use the version 3.2. it seems the MR job
didn’t work.

Hi, lianggang.
It would not appear immediately. It will start an MR job to calculate. After
a few minutes, you can check it again.

Hi liang,
Please check Yarn job history, Kylin will run an MR job to calculate the cardinality; If that job was failed, the cardinality won't be updated.
BTW, hive view is not supported for this function.
