[jira] [Commented] (SOLR-7342) zkcli command to delete node
[ https://issues.apache.org/jira/browse/SOLR-7342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14392925#comment-14392925 ]
Erick Erickson commented on SOLR-7342:
--------------------------------------
What about the DELETEREPLICA Collecitons API command? Maybe this could be enhanced somehow? I'm pretty sure it works even if a node isn't there, so having an incorrect IP address seems like it should be OK, but I don't know for sure.
> zkcli command to delete node
> ----------------------------
>
> Key: SOLR-7342
> URL: https://issues.apache.org/jira/browse/SOLR-7342
> Project: Solr
> Issue Type: Improvement
> Components: SolrCloud
> Affects Versions: 5.0
> Reporter: Shawn Heisey
> Priority: Minor
>
> Users encounter situations where SolrCloud detects the node IP address incorrectly, so a node gets inserted into the Zookeeper cluster with the incorrect address.
> It would be very useful if there were a command in zkcli to remove a node (host:port_context) from the SolrCloud cluster information stored in zookeeper. Manually editing the zookeeper database to remove a node is tedious and somewhat dangerous.
> Other situations where it would be useful are when a user needs to change the IP addressing on their SolrCloud cluster, and when an old node is retired.
