------------------------------------------------
> Avoid unsafe splits on URIs that might contain IPv6 literals
> ------------------------------------------------------------
>
> Key: HIVE-28782
> URL: https://issues.apache.org/jira/browse/HIVE-28782
> Project: Hive
> Issue Type: Sub-task
> Reporter: Dmitriy Fingerman
> Assignee: Dmitriy Fingerman
> Priority: Major
> Labels: pull-request-available
>
> Hive has code locations where it splits a URI on the first ":" assuming that
> it delimits a host from a port.
> This is unsafe in a dual-stack or IPv6-only world.
> * HS2ActivePassiveHARegistry.updateEndpoint
> * ZooKeeperHiveClientHelper.updateParamsWithZKServerNode
> Example:
> {code:java}
> final String[] tokens = instanceUri.split(":");
> final String hostname = tokens[0];
> final int port = Integer.parseInt(tokens[1]);{code}
> Similar issue in Hadoop:
