I just installed CLDB<FileServer<JobTracker<NFS<TaskTracker<WebServer<ZooKeeer in one node,because i want to test.

And I supposed **whether my disk is too low**,so lead to the problem.
Used the following command to set a storage
dd if=/dev/zero of=/root/storagefile bs=1G count=4
Asking for your help
