Viliam Durina created FLINK-6953:
------------------------------------

             Summary: Ignore space after comman in "high-availability.zookeeper.quorum"
                 Key: FLINK-6953
                 URL: https://issues.apache.org/jira/browse/FLINK-6953
             Project: Flink
          Issue Type: Improvement
          Components: Cluster Management, JobManager
    Affects Versions: 1.3.0
         Environment: Linux
            Reporter: Viliam Durina
            Priority: Minor


While trying to setup HA for JobManager, I configured the following:

{{high-availability.zookeeper.quorum: 10.0.0.179:2181, 10.0.0.176:2181}}

However, I got:

{{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 org.apache.flink.shaded.org.apache.curator.utils.DefaultZookeeperFactory.newZooKeeper(DefaultZookeeperFactory.java:29)
        ...
}}

Even though the IP address was available. The problem was the space after the comma. I suggest
to add some checks or, better, ignore the space, as this is a real pain to spot. Using the
space also makes the line more readable, and there is also space after the colon, which I
guess is optional.
