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)
...}}
The IP address was obviously 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.
