[Question:]The version of HDP sandbox for set up kylin dev environment

[??????????]

Hi, any engineer, could you tell me which version of HDP sandbox that you use 
for developing Kylin 2.6.0?Please. As we can see, the doc show that the version 
of HDP sandbox used for set up kylin dev env is 2.4, it's jdk need to update to 
1.8. But I find that the latest version of kylin 2.6.0 can support Hadoop 3.0. 
So, those baffle me. Help me, please
