嘗試使用HCatStorer將數據存儲到Hive數據庫時遇到問題（）

我使用PIG將表數據存儲到使用HCatalog的配置單元數據庫中。我能夠加載和轉儲數據在PIG咕嚕外殼，但是當我試圖將存儲加載的數據到我創建爲myweather.weathertable1（myweather-database名稱，weathertable1 -table name1）使用以下命令嘗試使用HCatStorer將數據存儲到Hive數據庫時遇到問題（）

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

我遇到了以下錯誤：

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.] 
Details at logfile: /X/Y/pig_1436660283762.log

和日誌文件說：

固定上述問題的任何幫助，可能是非常可觀的。在此先感謝。

可能出現[在運行HCatalog時發生錯誤]的副本（http://stackoverflow.com/questions/31295980/getting-an-error-on-running-hcatalog） –

請嘗試用-useHCatalog選項開始養豬。它將加載必要的罐子。請參閱HCat docs

@Fred感謝您的回覆。在發佈此任務之前，我曾使用過pig-useHCatalog。我最終通過用org.apache.hive.hcatalog.pig.HCatStorer（）替換org.apache.hcatalog.pig.HCatStorer（）來解決問題。可悲的是，Apache配置單元文檔還沒有更新這個錯誤（https://cwiki.apache.org/confluence/display/Hive/HCatalog+LoadStore#HCatalogLoadStore-The-useHCatalogFlag）。 – Mohana
