Storm子进程supervisor频繁Down机问题

最近频繁遇到一个问题,storm在提交运行jar程序时,子进程supervisor总是挂机,导致无法运行jar项目,之前以为是环境的问题或是ZK的版本问题,后来查看supervisor.log的日志信息才发现问题所在。先来看看错误

问题原因
2017-10-11 09:50:06 b.s.event [ERROR] Error when processing event
这一句是说没有正常退出导致的storm错误

这里多说一点,那么我们应该怎样关闭storm才不会出现这种错误能,最简单的就是jps查看进程后杀死,先从在主。(kill -9 进程ID)

解决办法
1:先检测storm配置文件storm.yaml,是否配置属性storm.local.dir;
2:若配置了storm.local.dir属性,在配置的路径下删除supervisor和workers两个文件夹即可;
3:若没有配置storm.local.dir属性,则添加配置即可;
4:重新启动;

这里要说的是,storm的日志在storm的logs目录下,它分为ui.log、nimbus.log、supervisor.log等等,当那个进程出现问题就查看对应日志即可

以下是几个shell脚本供参考

(1)批量启动ZK脚本:zookeeperStart.sh

#!/bin/bash

#zk节点
zkhost='hadoop2004 hadoop2005 hadoop2006'

#启动zk节点
for zk in $zkhost
do
        ssh -T $zk <

(2)批量关闭ZK脚本:zookeeperShutdown.sh

#!/bin/bash

#zk节点
zkhost='hadoop2004 hadoop2005 hadoop2006'

#停止zkji进程
for zk in $zkhost
do
        echo zk节点 $zk 停止zookeeper...[ done ]
        ssh -T $zk <

(3)启动storm集群脚本:stormStart.sh

#!/bin/bash

#mbus节点
nimbusServers='hadoop2004'

#supervisor节点
supervisorServers='hadoop2005 hadoop2006'

#启动所有的nimbus
for nim in $nimbusServers
do
    ssh -T $nim </dev/null 2>&1 &
EOF
echo 从节点 $nim 启动nimbus...[ done ]
sleep 1
done

#启动所有的ui
for u in $nimbusServers
do
    ssh -T $u </dev/null 2>&1 &
EOF
echo 从节点 $u 启动ui...[ done ]
sleep 1
done

#启动所有的supervisor
for visor in $supervisorServers
do
    ssh -T $visor </dev/null 2>&1 &
EOF
echo 从节点 $visor 启动supervisor...[ done ]
sleep 1
done

(4)关闭storm集群脚本:stormShutdown.sh


#!/bin/bash

#mbus节点
nimbusServers='hadoop2004'

#supervisor节点
supervisorServers='hadoop2005 hadoop2006'

#停止所有的nimbus和ui
for nim in $nimbusServers
do
    echo 从节点 $nim 停止nimbus...[ done ]
    ssh $nim "kill -9 `ssh $nim ps -ef | grep nimbus | awk '{print $2}'| head -n 1`" >/dev/null 2>&1
    echo 从节点 $nim 停止ui...[ done ]
    ssh $nim "kill -9 `ssh $nim ps -ef | grep core | awk '{print $2}'| head -n 1`" >/dev/null 2>&1
done

#停止所有的supervisor
for visor in $supervisorServers
do
    echo 从节点 $visor 停止supervisor...[ done ]
    ssh $visor "kill -9 `ssh $visor ps -ef | grep supervisor | awk '{print $2}'| head -n 1`" >/dev/null 2>&1
done
