我正在使用PIG使用HCatalog将表数据存储到配置单元数据库中。我能够在PIG grunt shell中加载和转储数据，但是当我尝试使用以下命令将加载的数据存储到我创建为myweather.weathertable1(myweather-database name，weathertable1 -table name1)的HIVE表中时
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.]

解决上述问题的任何帮助都是非常可取的。
提前致谢。
最佳答案
请尝试使用-useHCatalog选项启动pig。它将加载必要的 jar 。请参阅HCat docs
