Re: Why we need gridtable?

It's an abstraction of the cube storage; this makes cube build and query code more clear and loose coupling. 2016-11-10 20:36 GMT+08:00 Ding Dinghua : > Hi, I am trying to understand kylin 1.5.3 query logic, but I found it > is much more difficult to understand than

Re: Cube Merge Error

If you're using the precise distinct count (or say bitmap) on a non-integer column, Kylin need build dictionary to do a string -> integer convertion. To support ultra high cardinality, the "global dictionary" should be selected as it has less memory footprint, which can support up to 2 billion

Re: 答复: hadoop2.2 imcompatible proble

You can try to compile Kylin source code with Hadoop 2.2; we never did that; There are some Hadoop API change (as Billy mentioned) so you need re-write some codes. Good luck! 2016-11-10 16:42 GMT+08:00 胡志华(万里通科技及数据中心商务智能团队数据分析组) < huzhihua...@pingan.com.cn>: > You mean , it's impossible to
