[jira] [Created] (ZOOKEEPER-2814) Ignore space after comma in
connection string
Viliam Durina created ZOOKEEPER-2814:
----------------------------------------
Summary: 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 org.apache.zookeeper.ZooKeeper.<init>(ZooKeeper.java:445)

...}}
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.
