Hbase 零和产生问题

我想在Hbase中的一列中存储零。所以，我在猪的剧本中做了以下几点

    data = load 'access_log_Jul95' using PigStorage(' ') as (ip:chararray, dash1:chararray, dash2:chararray, date:chararray, date1:chararray, getRequset:chararray, location:chararray, http:chararray, code:int, size:int);

splitDate = foreach data generate  0 AS size:int , ip as ip,  FLATTEN(STRSPLIT(date, ':')) as h;

groupedIp = group splitDate by h.$1;

然后我就这样做了

a = foreach groupedIp generate SUM(splitDate.size); 

这是在控制台上抛出的错误，如

 Could not infer the matching function for org.apache.pig.builtin.SUM as multiple or none of them fit. Please use an explicit cast

在这种情况下，有没有什么方法可以不用求和就写零，或者求和处理所有零的方法会很有帮助

谢谢。

试试这个-

data = load 'access_log_Jul95' using PigStorage(' ') as (ip:chararray, dash1:chararray, dash2:chararray, date:chararray, date1:chararray, getRequset:chararray, location:chararray, http:chararray, code:int, size:int);

splitDate = foreach data generate  0 AS size:int , ip as ip,  FLATTEN(STRSPLIT(date, ':')) as (h1:chararray,h2:chararray,h3:chararray);

groupedIp = group splitDate by h1;

a = foreach groupedIp generate SUM(splitDate.size);

同时提供您的示例数据…如果数据可用，将非常有用
