unable to add more servers in zookeeper quorum peers in flink 1.2

[kanagaraj . vengidasamy]

Hi All,



We are using flink 1.2  .  Unable to add more than one digit in server.x.  when 
I have more than one digit it is not allowing to start the zookeeper.  What I 
need to do if I want to keep more servers?



# ZooKeeper quorum peers

server.0= server1:2888:3888

server.1= server2:2888:3888

server.2= server3:2888:3888

server.3= server4:2888:3888

server.4= server5:2888:3888

server.5= server6:2888:3888

server.6= server7:2888:3888

server.7= server8:2888:3888

server.8= server9:2888:3888

server.9= server10:2888:3888

#server.10= server11:2888:3888

#server.11= server12:2888:3888



Thanks
