J'utilise la version hadoop 2.7.3 et après la configuration, namenode n'apparaît pas en jps. Quelqu'un peut-il dire quelle est la raison pour laquelle j'ai donné des autorisations correctes aux fichiers concernés. J'ai supprimé/tmp fichiers et recréé et après reformatage le même problème de namenode je suis confronté. Merci d'avance.Quelqu'un peut-il dire des raisons de ne pas montrer les démons hadoop en jps?
