Question

我正在尝试在我的本地计算机上配置hadoop-0.23.8。而且我遇到了以下异常。你们知道我做错了吗

我正在使用以下系统var

export HADOOP_OPTS="-Djava.security.krb5.realm=OX.AC.UK -Djava.security.krb5.kdc=kdc0.ox.ac.uk:kdc1.ox.ac.uk"

我也使用java 6并设置了以下变量HADOOP_PREFIX，HADOOP_HDFS_HOME和YARN_HOME。你能帮忙正确配置吗？

所以我的一个配置文件中有一个小错误，对此抱歉，但我找到了配置hadoop 0.23.8的一些重要信息。在etc / hadoop文件夹中创建一个名为hadoop-env.sh的文件，其中放置了JAVA_HOME，HADOOP_OPTS。等

需要帮助配置Hadoop 0.23.8
