             Summary: kylin并发构建全局字典时间过长
                 Key: KYLIN-4007
             Project: Kylin
          Issue Type: Bug
          Components: Job Engine
    Affects Versions: v2.6.1
            Reporter: mouxingya
         Attachments: WechatIMG20.png

When a dimension (user_id) is accurately calculated at the same time, the original data is
in the order of millions, and the rowkey has the encoding type fixed_lengrh and length 100.
It took a few hours or even failed in the build dimension dictionary step. After investigation,
it was found that there are concurrent processes that want to obtain the lock corresponding
to the cube / dict path, resulting in a deadlock.
