我正在使用色调访问配置单元服务。我使用

create table tablename(colname type,.....) 
row format delimited fields terminated by ',';
我上传了30万条记录的数据。但在执行以下查询时:

select count(*) from tablename;
它正在创建MapReduce作业,此时我收到以下警告,如何解决此警告

警告:未执行Hadoop命令行选项解析。使生效 工具接口并使用ToolRunner执行应用程序,以 补救这一点

完整日志:

这只是MapReduce发出的警告,因为Hive提交的作业没有实现该接口。这可以放心地忽略
