Yarn报错：Could not find any valid local directory for nmPrivate/

原因：

yarn.nodemanager.local-dirs和hadoop的hadoop.tmp.dir参数对应文件位置不一致

解决办法：

将hdfs-site.xml中hadoop.tmp.dir属性和yarn-site.xml中的yarn.nodemanager.local-dirs属性设置为相同路径

示例

hdfs-site.xml

<property>

        <name>hadoop.tmp.dir</name>

        <value>/home/suddev/dev/bd/app/tmp</value>

</property>

yarn-site.xml

<property>

        <name>yarn.nodemanager.local-dirs</name>

        <value>/home/suddev/dev/bd/app/tmp</value>

</property>

然后重启dfs和Yarn

./stop-dfs.sh

./stop-yarn.sh

./start-dfs.sh

./start-yarn.sh
