ECS上外网IP部署SPARK问题，求大神提示！！

在ECS上上部署SPARK，使用内网IP测试没问题，换成外网后在：



Re-format filesystem in Storage Directory /root/soft/apache/hadoop/hadoop-2.7.7/tmp/dfs/name ? (Y or N) Y
18/12/15 17:03:09 INFO client.QuorumJournalManager: Waited 18001 ms (timeout=60000 ms) for a response for hasSomeData. No responses yet.
18/12/15 17:03:10 INFO client.QuorumJournalManager: Waited 19002 ms (timeout=60000 ms) for a response for hasSomeData. No responses yet.


出错，应该是权限问题，但不知道怎么解决，求大神提示！！
