"submit' I got
“empty cube segment found:[2016112000_2016113000, do you want to merge
segments forcely?”

hi,
每个维度的基数有590万,当在rowkey中选择dict时,编译产生错误:
“Too high cardinality is not suitable for dictionary -- cardinality: 5978388“
所以修改了model, 没有定义rowkey, 对所有维度定义了全局字典,build成功,查询时报错:
“AppendTrieDictionary can't retrive value from id“

I improved the version from 1.5.4.1 to 1.6.0 and modified KYLIN_HOME, and
modied "kylin.dictionary.max.cardinality=500" to
"kylin.dictionary.max.cardinality=3000" in file kylin.properties,
then start kylin 1.6-->create model-->create cube-->build cube
I got the following error m
Hi
when I excute the sql:
(select t3.CATE1,count(*) from (select CATE1 ,CATE2 from kylinlabel.USER_TAG
group by CATE1 ,CATE2) as t3 group by t3.CATE1) as t4
right join
(select cate1 from kylinlabel.USER_TAG group by cate1) as t5 on
(t4.cate1=t5.cate1)
I got the error:
Encountered "as"
