以下を使用して許可が拒否される可能性はありますか? 私はpython 2.7とubuntu 12.04を使用しています

以下は私のmapper.pyファイルです

import sys
import json

for line in sys.stdin:
    line = json.loads(line)
    key = "%s:%s" % (line['user_key'],line['item_key'])
    value = 1
    sys.stdout.write('%s\t%s\n' % (key,value))

以下は私のデータファイルです

あなたのmapper.pyファイルは実行可能である必要があります（実行可能なパーティション上で）chmod a+x mapper.py

基礎となるexecve(2)システムコールが失敗しています

   EACCES Execute permission is denied for the file or a script or ELF
          interpreter.

   EACCES The file system is mounted noexec.

次のように、コマンドに「python」を追加できます

cat /home/ubuntu/workspace/logging/data.txt | python /home/ubuntu/workspace/logging/mapper.py
