>                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2814
>             Project: ZooKeeper
>          Issue Type: Bug
>    Affects Versions: 3.5.3
>            Reporter: Viliam Durina
>            Assignee: Nikhil Ashok Bhide
>            Priority: Minor

> I'm using the following connection string:
> {{10.0.0.179:2181,<space>10.0.0.176:2181}}
> However, I get:
> {{java.net.UnknownHostException: 10.0.0.176: Name or service not known
> at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
> at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:928)
> at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1323)
> at java.net.InetAddress.getAllByName0(InetAddress.java:1276)
> at java.net.InetAddress.getAllByName(InetAddress.java:1192)
> at java.net.InetAddress.getAllByName(InetAddress.java:1126)
> at org.apache.zookeeper.client.StaticHostProvider.<init>(StaticHostProvider.java:61)
> at org.apache.zookeeper.ZooKeeper.<init>(ZooKeeper.java:445)
> at ...
> ...}}
> The problem was the space after the comma. I suggest to either make the space optional
or produce error on it, as this is a real pain to spot. Using the space also makes the connect
string more readable. Spaces are not allowed in domain names.
