Hadoop Thread-daemon.sh写入HDP中的错误日志目录

我已经在笔记本电脑上安装了Hortonworks HDP版本2.2.4.2-2。我已经启动了HDFS服务，例如名称节点、辅助名称节点和所有数据节点。我可以通过名称节点web界面浏览HDFS。问题在于资源管理器。HDP伴随文件为

HADOOP\u LIBEXEC\u DIR

设置了错误的值。它被设置为

/usr/lib/hadoop/libexec

，这是错误的。正确的地址是：

/usr/hdp/2.2.4.2-2/hadoop/libexec

。更改此参数并使用此命令启动资源管理器（使用

warn

user）后：

它显示错误：

mkdir: cannot create directory `/var/log/hadoop-yarn': Permission denied
chown: cannot access `/var/log/hadoop-yarn/yarn': No such file or directory
mkdir: cannot create directory `/var/run/hadoop-yarn': Permission denied

/usr/hdp/current/hadoop-yarn-resourcemanager/sbin/yarn-daemon.sh: line 136: /var/log/hadoop-yarn/yarn/yarn-yarn-resourcemanager-rm.hdp.local.out: No such file or directory

问题是

线程守护进程。根据我的环境变量，sh

使用了错误的日志目录：

[yarn@rm ~]$ echo ${YARN_LOCAL_DIR}
/hadoop/yarn/local
[yarn@rm ~]$ echo ${YARN_LOG_DIR}
/var/log/hadoop/yarn
[yarn@rm ~]$ echo ${YARN_LOCAL_LOG_DIR}
/hadoop/yarn/logs
[yarn@rm ~]$ echo ${YARN_PID_DIR}
/var/run/hadoop/yarn

这真的是一个bug还是我做错了什么？

您正在使用的启动脚本，即/usr/hdp/current/hadoop warn resourcemanager/sbin/warn-daemon.sh，在您的案例中，用于获取位于您指定的配置目录中的warn-env.sh脚本

--config/etc/hadoop/conf

这些环境变量很可能在该脚本中被重写。如果您使用的是Hortonwork提供的配套文件，则这些文件确实被更改为：

export YARN_LOG_DIR=/var/log/hadoop-yarn/$USER
export YARN_PID_DIR=/var/run/hadoop-yarn/$USER
export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec

最好将/etc/hadoop/warn-env.sh脚本中的这些值更改为所需的值，然后重试

export YARN_LOG_DIR=/var/log/hadoop-yarn/$USER
export YARN_PID_DIR=/var/run/hadoop-yarn/$USER
export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec
