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

        hadoop.tmp.dir
        /home/suddev/dev/bd/app/tmp

yarn-site.xml

        yarn.nodemanager.local-dirs
        /home/suddev/dev/bd/app/tmp

然后重启dfs和Yarn

./stop-dfs.sh
./stop-yarn.sh
./start-dfs.sh
./start-yarn.sh
