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