Spark kümelenmesinin birden çok düğümünde Apache Spark kullanarak bir Windows toplu iş dosyasını çalıştırmam gereken bir gereksinim var.Bir Windows Batch Dosyasını Apache Spark içinde Piping ile Çalıştırma
Aynı şekilde, Apache Spark'ın Piping konseptini kullanarak da aynısını yapmak mümkün müdür?
Ubuntu makinesinde Spark içinde Piping kullanarak bir kabuk dosyası çalıştırmadan önce var. Aynı şeyi Aşağıdaki kodum iyi çalışır:
data = ["hi","hello","how","are","you"]
distScript = "/home/aawasthi/echo.sh"
distScriptName = "echo.sh"
sc.addFile(distScript)
RDDdata = sc.parallelize(data)
print RDDdata.pipe(SparkFiles.get(distScriptName)).collect()
Ben Bir Windows makine olan Spark bir Windows toplu iş dosyası yüklü (Hadoop'un 2.6 için 1.6 önceden oluşturulmuş) çalıştırmak için aynı kodu ayak uydurduk. Ama bana sc.addFile adımında hata veriyor. Kod aşağıdadır: Kıvılcım tarafından atılan
batchFile = "D:/spark-1.6.2-bin-hadoop2.6/data/OpenCV/runOpenCv"
batchFileName = "runOpenCv"
sc.addFile(batchFile)
Hata aşağıdaki gibidir: toplu iş dosyası verilen bir konumda bulunuyorsa
Py4JJavaError Traceback (most recent call last)
<ipython-input-11-9e13c265cbae> in <module>()

rağmen.
GÜNCELLEME: Dosya yolunun başlangıç içinde batchFile & batchFileName & file:/// yılında uzantısı olarak
Eklendi .bat. Modifiye kodudur:
from pyspark import SparkFiles
from pyspark import SparkContext
sc
batchFile = "file:///D:/spark-1.6.2-bin-hadoop2.6/data/OpenCV/runOpenCv.bat"
batchFileName = "runOpenCv.bat"
sc.addFile(batchFile)
RDDdata = sc.parallelize(["hi","hello"])
print SparkFiles.get("runOpenCv.bat")
print RDDdata.pipe(SparkFiles.get(batchFileName)).collect()
addFile adımda hata vermek ve
print SparkFiles.get("runOpenCv.bat") baskılar patikayı
C:\Users\abhilash.awasthi\AppData\Local\Temp\spark-c0f383b1-8365-4840-bd0f-e7eb46cc6794\userFiles-69051066-f18c-45dc-9610-59cbde0d77fe\runOpenCv.bat
Yani dosya eklenir etmez. Ama kodunun son adımında aşağıda hata atıyor:

Windows toplu iş dosyalarında '.cmd' veya' .bat' uzantılı. Eklemeye çalıştın mı? –
@MCND Oh aptal benim ... İsim uzerinde orada olmalı. 'BatchFile' ve' batchFileName' içinde '.bat' ekledikten sonra, dosyada hata bulunmuyor. Ancak güncellenmiş cevapta gösterildiği gibi farklı hatalar alıyorum. –
'Şema için Dosya Sistemi yok: D ', yani D:' gerektiği gibi ele alınmıyor, belki (bu aptalca bir şey varsa, toplu iş dosyaları hakkında bir şeyler biliyorum, ama java alanım değil) bir URI'ye ihtiyacınız var 'file: /// D:/...' gibi olması gerekiyor –
