尝试执行非事务性更新 table 时出现 Hive 错误

Question

我正在尝试使用以下命令更新配置单元上的临时 table：

alter table para1 add columns(log_flag int);
update para1 set log_flag = (
  case 
            when name like '%LANDING__TIME' then 1 
            when name like '%LOGIN_START_TIME' then 2
            when name like '%LOGIN_TIME' then 3
            else 4
  end
  );

以下是我收到的错误：

ERROR: Execute error: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: SemanticException [Error 10297]: Attempt to do update or delete on table df.para1 that is not transactional

这阻止我用新的条件变量 log_flag 更新 table，我真的不确定是什么原因。

感谢您的帮助！

对非事务使用 INSERT OVERWRITE table:

INSERT OVERWRITE table para1
select 
     col1, ... coln, --list all other columns (columns positions should match)
     case 
            when name like '%LANDING__TIME'    then 1 
            when name like '%LOGIN_START_TIME' then 2
            when name like '%LOGIN_TIME'       then 3
            else 4
    end as log_flag 
from para1;
