Nikhil Ashok Bhide commented on ZOOKEEPER-2814: ----------------------------------------------- Spaces are not allowed in the domain space. So, would it be good idea to trim the spaces and use the address or throw exception that IP address/host name of server can not contain space? According to me, its better to throw the exception rather than trimming spaces of provided IP address. > Ignore space after comma in connection string > --------------------------------------------- > > Key: ZOOKEEPER-2814 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2814 > Project: ZooKeeper > Issue Type: Bug > Affects Versions: 3.5.3 > Reporter: Viliam Durina > 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.
