[jira] [Updated] (FLINK-6953) Ignore space after comman in "high-availability.zookeeper.quorum"

     [ https://issues.apache.org/jira/browse/FLINK-6953?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Viliam Durina updated FLINK-6953:
---------------------------------
    Description: 
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.
