我使用PIG使用HCatalog将表数据存储到hive数据库中。我能够在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HIVE表中时，我使用下面创建的myweather.weathertable1（myweather-database name，weathertable1 -table name1）命令
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.]
