OSX 上的 Hadoop“无法从 SCDynamicStore 加载领域信息" [英] Hadoop on OSX "Unable to load realm info from SCDynamicStore"

问题描述

我在 OSX 10.7 上启动 Hadoop 时遇到此错误:

I am getting this error on startup of Hadoop on OSX 10.7:

无法从 SCDynamicStore 加载领域信息放置:org.apache.hadoop.hdfs.server.namenode.SafeModeException:无法创建目录/user/travis/input/conf.名称节点处于安全模式.

Unable to load realm info from SCDynamicStore put: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create directory /user/travis/input/conf. Name node is in safe mode.

它似乎不会导致 Hadoop 的功能出现任何问题.

It doesn't appear to be causing any issues with the functionality of Hadoop.

推荐答案

Matthew Buckett 在 HADOOP-7489 中的建议对我有用.将以下内容添加到您的 hadoop-env.sh 文件中:

Matthew Buckett's suggestion in HADOOP-7489 worked for me. Add the following to your hadoop-env.sh file:

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