Subject [jira] [Commented] (SOLR-7342) zkcli command to delete node
Date Thu, 02 Apr 2015 16:39:53 GMT


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.

>                 Key: SOLR-7342
>                 URL:
>             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.
