Hi, all
Two questions :
1# The sample cube generated one measure listed as below. Notice that the
return type goes to bigint, however, if we create a cube for our own
and define such measure of count_distince expression, the return type seems
to be hllc(int) and no way to be bigint. How could that be generated in the
sample cube ?
6 SELLER_CNT_LONG COUNT_DISTINCT column SELLER_ID bigint
2# According to the tutorial guide, Only accept single column in param value
with "Column" type. However, the sample cube ui listed as below just show that
the measure
contains 2 param value as LSTG_FORMAT_NAME and SELLER_ID. Quite weird with
the issue.
7 SELLER_FORMAT_CNT COUNT_DISTINCT column LSTG_FORMAT_NAME,SELLER_ID
hllc(10)
AND, the tutorial listed here seems to be for older release versions of kylin,
maybe should go for an upgrade :

Thanks for your attention,
Sun.
