[jira] [Commented] (CASSANDRA-5865) NPE when you mistakenly set
listen_address to 0.0.0.0
[ https://issues.apache.org/jira/browse/CASSANDRA-5865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13734868#comment-13734868 ]
Jonathan Ellis commented on CASSANDRA-5865:
-------------------------------------------
Shouldn't we make it reject invalid addresses instead of starting up and NPEing later?

> Key: CASSANDRA-5865
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5865
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 1.2.8
> Reporter: Michaël Figuière
> Priority: Trivial
>
> It's clearly stated that setting {{listen_address}} to {{0.0.0.0}} is always wrong. But if you mistakenly do it anyway you end up with an NPE on 1.2.8 while it's not the case on 2.0.0-rc1. See bellow:

Otherwise, you need to determine why the seed being contacted has no knowledge of the rest of the cluster. Usually, this can be solved by giving all nodes the same seed list.
