Błędy „Odmowa zezwolenia” podczas uruchamiania klastra z jednym węzłem w Hadoop

Pracuję w Ubuntu 10.10 i próbuję uruchomić klaster z pojedynczym węzłem w Hadoop.

hadoop@abraham-Dimension-3000:/usr/local/hadoop$ 

Nie mam pojęcia, co robię źle lub co sugerują niektóre z tych błędów.

hadoop@abraham-Dimension-3000:/usr/local/hadoop$ jps
5099 Jps

Czy każdy może zdiagnozować problem.

Błędy sugerują problem z uprawnieniami.

Upewnij się, że użytkownik hadoop ma odpowiednie uprawnienia /usr/local/hadoop. Próbować:

sudo chown -R hadoop / usr / local / hadoop /

podałeś katalog roboczy dla systemu plików hadoop z innym użytkownikiem niż hadoop, więc ustaw katalog, który ma odczyt, uprawnienia do zapisu dla użytkownika hadoop lub zmień uprawnienia katalogu
Spróbuj ::

sudo chown -R hadoop-user /user/hadoop_project/

lub

sudo chmod 777 /user/hadoop_project

gdzie nazwa użytkownika „hadoop-user” dla środowiska hadoop. „hadoop-project” określił katalog roboczy dla systemu plików hadoop. (podaj własny login i katalog, którego używasz do instalacji hadoopa)
