Subject [jira] [Created] (SPARK-22180) Allow IPv6 address
Date Sun, 01 Oct 2017 13:14:00 GMT
Stefan Obermeier created SPARK-22180:
----------------------------------------

             Summary: Allow IPv6 address
                 Key: SPARK-22180
                 URL: https://issues.apache.org/jira/browse/SPARK-22180
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.2.0
            Reporter: Stefan Obermeier
            Priority: Critical


External applications like Apache Cassandra are able to deal with IPv6 addresses. Libraries
like spark-cassandra-connector combine Apache Cassandra with Apache Spark.
This combination is very useful  IMHO. 

One problem is that  {code:java} org.apache.spark.util.Utils.parseHostPort(hostPort: String)
{code} takes the last colon to sepperate the port from host path. This conflicts with literal
IPv6 addresses.

I think we can take {code}hostPort{code} as literal IPv6 address if it contains tow ore more
colons. If IPv6 addresses are enclosed in square brackets port definition is still possible.
