Hi, Is it possible to modify a cube already built, such as adding new metrics or dimensions? Is it possible to rename cube columns? I have not seen anything about this type of common needs in the current Kylin documentation. I have tried to add a new metric but Kylin do not allow to save new

Hi Zhimin, Thanks for the reminder; I will review and merge it. 在 2018年4月4日 下午7:01，小村庄 写道： > cube中，设计rowkey时，有个维度设置编码方式是固定长度500。每天采用内存构建算法。在合并cube时，在生成的mr中的map任务执行中出现“ > java.lang.ArrayIndexOutOfBoundsException at java.lang.System.arraycopy(Native > Method)”

When merge cube??get java.lang.ArrayIndexOutOfBoundsException at java.lang.System.arraycopy(Native Method)

cuberowkey??500??cubemrmapjava.lang.ArrayIndexOutOfBoundsException at java.lang.System.arraycopy(Native Method)??

Its not working even though I have set up the properties. In jSON file, I have given the DB name db_rft_rcmo_rfda. Why its creating DB name as Kylin? How can we change it & make it configurable Hive DB name. -bash-4.1$ ls -ltr total 20 -rw--- 1 a_rcmo_nd a_rcmo_grp 1976 Apr 2 08:59
