             Summary: “Build N-Dimension Cuboid” execute twice when using DistributedScheduler
                 Key: KYLIN-4802
                 URL: https://issues.apache.org/jira/browse/KYLIN-4802
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.6.6
            Reporter: WangSheng
         Attachments: kylin01.png, kylin02.png, kylin03.png

I met a problem when using DistributedScheduler in two node, my current cluster version is 2.6.6. When executing "Build N-Dimension Cuboid : level 4" step, I found this step submitted MR job in both two nodes. One node submitted a MR first,  and then executed following steps, when executing "Convert Cuboid Data to HFile" step, another node submitted a MR for "Build N-Dimension Cuboid : level 4" step again. And this caused data missing when generated File. And after this job completed, query on level 4 returns empty.
