             Summary: step "Building Cube" takes 20 hours +
                 Key: KYLIN-1618
                 URL: https://issues.apache.org/jira/browse/KYLIN-1618
             Project: Kylin
          Issue Type: Improvement
          Components: Tools, Build and Test
    Affects Versions: v1.5.1
         Environment: hadoop 2.6.0
hbase 0.98
kylin1.5.1
            Reporter: huzhihua
            Assignee: hongbin ma
            Priority: Minor


 I upgrade kylin from 1.3 to 1.5.1, so i build a cube for testing. But the build lasts so long time than i think there must be something wrong with my cluster or kylin.properties. I wonder whether i can modify something about cluster configuration (such as mapreduce-site.xml )or kylin.properties to accelerate the progress,

I just select 1-2 partitions from the fact table, so the data is not so big.

info about hadoop cluster:
job name :Kylin_Cube_Builder_11

memory used/total : 4G/120G
vcores used/total:2/96
map/reduce 1
