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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
