      Description

      Error log was as follows,

      org.apache.kylin.common.persistence.WriteConflictException: Overwriting conflict /user/admin, expect old TS 1536928877043, but it is 1536928907207

      what disturbs me the most was that the error was happened several hours,  then my all build job and query job failed.
