pig で簡単なスクリプトを作成しましたが、ターミナルから実行するとうまく動作します。
ただし、Apache サーバーを使用してブラウザーからスクリプトを実行しようとすると、次のエラーがスローされます。
[main] ERROR org.apache.pig.tools.grunt.Grunt - You don't have permission to perform the operation. Error from the server: dummy (Permission denied)
[main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2997: Encountered IOException. dummy (Permission denied)
問題を解決するためのアイデアはありますか? それが役に立ったら、スクリプトのどこにも「ダミー」と呼ばれるものを使用していません!!!
PS: /tmp hdfs ディレクトリの権限を 777 に変更しましたが、役に立ちませんでした!!
/tmp ローカル ディレクトリの権限が 777 であることを確認しましたが、問題ありませんでした!!
-Dpig.temp.dir を apache が書き込み権限を持つディレクトリに使用しようとしましたが、役に立ちませんでした!!
助けてください、私は何かを逃しましたか？
編集：言及する価値があります：このエラーは、豚スクリプトのコンパイルをチェックしているときにスクリプトを実行しているときに発生します。つまり、 pig -c ScriptName
