我正在使用pig使用hcatalog将表数据存储到配置单元数据库中。我可以在pig grunt shell中加载和转储数据，但是当我试图将加载的数据存储到配置单元表中时，我使用下面的命令创建了myweather.weathertable1（myweather数据库名称，weathertable1-表名称1）

STORE A INTO 'myweather.weathertable1' USING org.apache.hcatalog.pig.HCatStorer();

我遇到以下错误：

2015-07-11 20:20:09,056 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1070: Could not resolve org.apache.hcatalog.pig.HCatStorer using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

日志文件上写着：
