检查一下网络，看这几台能ping通吗
TimeoutException: Conversation-response mapping: {1/13#=ResponseFuture{conversationId=‘1/13#’, initiatedByMessageType=join, response=null}}
网络没问题，可以ping通 [root@master hadoop]# ping slave1 PING slave1 (172.16.247.132) 56(84) bytes of data. 64 bytes from slave1 (172.16.247.132): icmp_seq=1 ttl=64 time=0.343 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=2 ttl=64 time=0.784 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=3 ttl=64 time=0.239 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=4 ttl=64 time=0.898 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=5 ttl=64 time=1.15 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=6 ttl=64 time=0.773 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=7 ttl=64 time=0.586 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=8 ttl=64 time=0.764 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=9 ttl=64 time=0.691 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=10 ttl=64 time=0.626 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=11 ttl=64 time=1.00 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=12 ttl=64 time=0.728 ms 64 bytes from slave1 (172.16.247.132): icmp_seq=13 ttl=64 time=0.908 ms ^C — slave1 ping statistics — 13 packets transmitted, 13 received, 0% packet loss, time 12007ms rtt min/avg/max/mdev = 0.239/0.730/1.153/0.241 ms [root@master hadoop]# ping slave2 PING slave2 (172.16.247.136) 56(84) bytes of data. 64 bytes from slave2 (172.16.247.136): icmp_seq=1 ttl=64 time=0.695 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=2 ttl=64 time=0.690 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=3 ttl=64 time=0.719 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=4 ttl=64 time=0.755 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=5 ttl=64 time=0.749 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=6 ttl=64 time=0.981 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=7 ttl=64 time=0.786 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=8 ttl=64 time=0.867 ms 64 bytes from slave2 (172.16.247.136): icmp_seq=9 ttl=64 time=0.550 ms ^C — slave2 ping statistics — 9 packets transmitted, 9 received, 0% packet loss, time 8006ms rtt min/avg/max/mdev = 0.550/0.754/0.981/0.117 ms
