Опитвам се да изпълня задача на mapreduce за анализ на XML, използвайки библиотека mahout 0.9 на Hadoop 2.2. Но получавам следната грешка:
14/02/24 16:03:02 INFO mapreduce.Job: Task Id : attempt_1393235568433_0004_m_000000_0, Status : FAILED

Job failed as tasks failed. failedMaps:1 failedReduces:0
Опитах се да потърся решение, но получих връзката http://osdir.com/ml/general/2014-02/msg39414.html , който гласи, че Mahout 0.8 или 0.9 не се поддържа за Hadoop 2.2.
Възможно ли е някакво решение??
