Dear
关于kylin 函数的问题请教一下：
业务场景： TopN查询
在hive中可以使用开窗函数，诸如：
select row_number() over (partition by part_dt order by item_count) as row1
,part_dt, item_count from kylin_sales;
再Kylin 中建立cube的时候 ,如何来控制？
谢谢

Re
our suggestion for new users is to leverage hdp sandbox which is free to
download. some guy helped us build a docker in the very early stage of
Kylin, however it is out of maintenance and honestly speaking maintaining
the docker image is an extra burden for us.

ShaoFeng Shi is right, kylin use hive command to generate intermediate
table(take it as source data), and use hcatlog get data from hive in step2,
hive performance does have an impact on Kylin's performance, so a newer
version is recommended。

Only the first step actually, Kylin runs "hive -e" command to create an
intermediate table; The following steps are running MR over the files under
that table.

Hi Yu and Everyone,
Just a little bit supplement, Hive definitely involves in the step of Create
Intermediate Flat Hive Table and Build Dimension Dictionary. The question
is that does Hive involve in the following steps of building cuboids?

Hi Yu,
How is Kylin retrieving the data? Is it using Hive only for the metadata?
Or is it using Hive to retrieve the data for it?
If Kylin use Hive to retrieve the data for the build, then won't
performance of hive have an impact on Kylin's performance
as well?
I've also done some research for th
Agreed. Docker is not a silver bullet. But to get a quick start with Kylin
without a distro is time consuming. And for people who are new to Kylin and
want to quickly do a sample cube build to get the feel of the product it
will be great to include the latest stable version of Kylin in Docker.

you can comment out all entries containing snappy in kylin_hive_conf.xml,
kylin_job_conf.xml and kylin.properties (find them in $KYLIN_HOME/conf)
in that case MR will use no compression, and storage in hbase will not use
any, either.

因为我使用的hadoop为2.6的版本，为官方的二进制包，测试发现不支持Snappy压缩，kylin在运行job想换个压缩方式，那么mapred.map.output.compression.codec这个参数可以配置为的value有哪些？
我的配置kylin_job_conf.xml：
mapred.map.output.compression.codec
org.apache.hadoop.io.compress.SnappyCodec
The compression codec to use for map outputs

Well, it's very old and stable. :-)
We shall check the new Hadoop Job API.
