Warum hat Hadoop in Windows7 eine RuntimeException ausgelöst: Fehler beim Konfigurieren des Objekts

Question

Ich versuche, in Windows7 ein Hadoop-Programm im pseudoverteilten Modus auszuführen, und eine RuntimeException wurde ausgelöst. Ich weiß nicht warum und wie ich es beheben kann.

Ich benutze Python für mapreduce Arbeit statt Java mit Hadoop-Streaming-Dienstprogramm (https://hadoop.apache.org/docs/current/hadoop-streaming/HadoopStreaming.html). Ich lief hadoop jar %HADOOP_HOME%\share\hadoop\tools\lib\hadoop-streaming-2.6.2.jar -mapper mapper.py -reducer reducer.py -input myinput -output myoutput -file mapper.py -file reducer.py und ein java.lang.RuntimeException: Error in configuring object wurde ausgelöst und Job fehlgeschlagen.

Meine Hadoop-Version ist 2.6.2, und Hadoop ist auf Windows7 x64, nicht auf der virtuellen Maschine oder Cygwin gebaut.

Zuerst habe ich das Standard-Testprogramm von hadoop verwendet, um zu testen, ob hadoop erfolgreich installiert wurde. Ich lief yarn jar %HADOOP_HOME%/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.2.jar pi 16 1000 und die Ausgabe ist korrekt. Hadoop und MapReduce arbeiten.

Zweitens wurden die Mapper.py und Reducer.py unter Eingabeaufforderung mit Befehl cat data.txt | python mapper.py | sort | python reducer.py getestet und die Ausgabe ist korrekt. Daher wäre es nicht der Bug des Python-Programms.

Ich versuche, die Eigenschaft 'hadoop.tmp.dir' in das lokale Verzeichnis und/tmp zu ändern, aber keiner von beiden hat funktioniert. Ich weiß nicht, warum die Ausnahme ausgelöst wurde und wie sie zu beheben ist. Vielen Dank, wenn mir jemand helfen kann!

Das komplette Ausnahmeprotokoll ist wie folgt:

Answer 1

Die Werte der -mapper und -reducer Befehlszeilenargumente müssen ausführbare Dateien sein. Unter Windows, das Shebang-Zeilen nicht unterstützt, sind Python-Skripte nicht ausführbar.

Versuchen Sie, die -mapper und -reducer Argumente wie folgt spezifiziert:

-mapper "python mapper.py" -reducer "python reducer.py" 

Bitte beachten Sie, dass ich mich nicht laufen diese so garantieren kann ich nicht, dass es funktionieren wird. Es kann sich beschweren, dass es eine Datei mit dem Namen python mapper.py nicht finden kann.

Wenn dies nicht funktioniert, schreiben Sie kurze Batch-Skripts und reducer.bat, die nur das entsprechende Python-Skript ausführen. Zum Beispiel würde mapper.bat die folgenden Zeilen enthalten:

@echo off 
python mapper.py %* 

Dann diese Batch-Skripten als -mapper und -reducer Argumente angeben. Fügen Sie außerdem die Befehlszeilenargumente -file mapper.bat und -file reducer.bat hinzu, um sicherzustellen, dass diese Stapelskripte auf alle Ihre Rechenknoten kopiert werden.
