Sto utilizzando Hadoop in finestre e ho configurato tutto il bene (l'installazione di Cygwin, ssh senza password, ecc ..)Hadoop in Windows: file non trovato eccezione
ho compilato il programma wordcount in WC.jar e ho provato a correre. Funziona perfettamente in modalità standalone .. ma in modalità completamente distribuita dà FileNotFoundException
Si prega di guardare nei registri e tel me cosa c'è di sbagliato con esso. ho avviato il dfs e il mapreduce nel MACH1. (questo è il mio master)
