I am facing same issue in cube building. First kylin give best result for 12
dimensions as this property is set in kylin.property file
*kylin.cube.aggrgroup.max.combination=4096* so 2^12 . if you want best
performance add Join dimensions,hierarchy(country,state,region,city) and
Mandatory(high cardi
Hello All,
I found 3 reason why its not working.
1. Permission issues on HDFS level.
2. For kylin up-gradation if you overwrite old property file than it will
give "kylin.env.hdfs-working-dir" error.
3. JAVA VERSION you need to have 1.7 or above java version.
I hope it may help you.
Thanks
