我正在使用Hortonworks Sandbox 1.2，而且我對Hadoop平臺很新。Hadoop PIG Helper GROUP錯誤
所以這裏是錯誤，而我正在按照沙箱包含的教程。在PIG部分，我使用PIG Helper插入了GROUP代碼。它插入一個代碼，如
GROUP %VAR% BY %VAR%
而我的代碼看起來像這樣，我完成教程後。就像是在教程告訴
[main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: mismatched input ';' expecting LEFT_PAREN
我做的一切：
a = LOAD 'nyse_stocks' USING org.apache.hcatalog.pig.HCatLoader();
b = FILTER a BY stock_symbol == 'IBM';
c = GROUP b BY all;
d = FOREACH c GENERATE AVG(b.stock_volume);
DUMP d;
它提供了以下錯誤。那麼錯誤在哪裏？編輯： 我在下面添加了PIG日誌。

你可以粘貼豬日誌嗎？ – zsxwing
我添加了豬日誌。我通過改變GROUP epression來解決問題。剛剛刪除關鍵字，它的工作。 –
