      Description

      If the below query submitted several times concurrently, the result could be: All these queries finished, and table created in HMS, but not exists  in kudu storage. I've already found the reason, and I will submit the patch later.

      create table if not exists test_kudu_table(
        logDay string,
        id int,
        primary key(logDay,id)
      )
      PARTITION BY RANGE (logDay)
      (PARTITION VALUE = '2019-09-20')
      STORED AS KUDU TBLPROPERTIES ('kudu.master_addresses'='master1:7051,master2:7051,master3:7051');
