hdfs yarn hbase pid文件被删除解决办法：修改hadoop-daemon.sh yarn-daemon.sh hbase-daemon.sh中PID_DIR存储路径

pid内容为各进程的进程号  
通过ps -ef | grep a 查询a的pid，精确杀死某进程  
\[hadoop@hadoop000 sbin\]$ cat hadoop-daemon.sh |grep pid

HADOOP\_PID\_DIR The pid files are stored. /tmp by default.（ pid默认存储在/tmp目录）

pid= H A D O O P P I D D I R / h a d o o p − HADOOP\_PID\_DIR/hadoop- HADOOPPIDDIR/hadoop−HADOOP\_IDENT\_STRING-$command.pid  
if \[ -f $pid \]; then  
if kill -0 `cat $pid` > /dev/null 2>&1; then  
echo $command running as process `cat $pid`. Stop it first.  
echo $! > $pid  
if \[ -f $pid \]; then  
TARGET\_PID=`cat $pid`  
rm -f $pid

删除pid，进程不挂，服务正常

生产上:  
pid 最好不要放到/tmp，若要放到/tmp目录，则需要修改自动清理机制。  
/tmp目录默认：一个月清理一次临时文件

修改pid路径步骤：  
1.先修改sbin目录下hadoop-daemon.sh文件

指定HADOOP\_PID\_DIR储存路径

2.再修改 yarn-daemon.sh 文件

![img][img 1]

指定YARN\_PID\_DIR储存路径

3.重新启动Hadoop：  
会看的刚才指定的pid路径  
hadoop-2.8.1\]$ ll  
total 164  
drwxrwxr-x. 2 hadoop hadoop 4096 Jul 6 04:53 bin  
drwxrwxr-x. 3 hadoop hadoop 4096 Jun 2 2017 etc

drwxrwxr-x. 4 hadoop hadoop 4096 Jun 2 2017 share  
4.目录pid里面的内容：  
hadoop-2.8.1\]$ ll pid  
total 20  
\-rw-rw-r–. 1 hadoop hadoop 5 Jul 7 21:12 hadoop-hadoop-datanode.pid  
\-rw-rw-r–. 1 hadoop hadoop 5 Jul 7 21:12 hadoop-hadoop-namenode.pid  
\-rw-rw-r–. 1 hadoop hadoop 5 Jul 7 21:13 hadoop-hadoop-secondarynamenode.pid  
\-rw-rw-r–. 1 hadoop hadoop 5 Jul 7 21:13 yarn-hadoop-nodemanager.pid  
\-rw-rw-r–. 1 hadoop hadoop 5 Jul 7 21:13 yarn-hadoop-resourcemanager.pid

修改成功
