原因是电脑突然断电，未正常退出storm所导致。

解决办法是删除storm配置文件中storm.local.dir所指向的目录中的supervisor和workers两个文件夹。

[zzq@weekend116 bin]$ sudo find / -name supervisor
[sudo] password for zzq: 
/home/zzq/storm-local/supervisor
/home/zzq/app/apache-storm-0.9.2-incubating/bin/storm-local/supervisor
[zzq@weekend116 bin]$ rm -rf /home/zzq/storm-local/supervisor
[zzq@weekend116 bin]$ rm -rf /home/zzq/app/apache-storm-0.9.2-incubating/bin/storm-local/supervisor
[zzq@weekend116 bin]$ sudo find / -name workers
[sudo] password for zzq: 
/home/zzq/storm-local/workers
[zzq@weekend116 bin]$ rm -rf /home/zzq/storm-local/workers

现在启动成功了：
