Timothy Potter closed SOLR-6571.
--------------------------------
Resolution: Won't Fix
Looks like ZkIndexSchemaReader is the only place where this isn't done
correctly so there's not really any general problem here. Will fix the schema
reader as part of SOLR-6249
> Need a znode watcher support class

> Key: SOLR-6571
> URL: https://issues.apache.org/jira/browse/SOLR-6571
> Project: Solr
> Issue Type: Improvement
> Components: SolrCloud
> Reporter: Timothy Potter
>
> When implementing SOLR-6249, [~noble.paul] points out that
> ZkIndexSchemaReader doesn't watch the managed schema znode correctly and
> should use a strategy similar to what ZkStateReader does so that watchers
> persist across zk client connection failures:
> The correct example is the constructor of ZkStateReader
> zkClient = new SolrZkClient(zkServerAddress, zkClientTimeout,
> zkClientConnectTimeout,
> // on reconnect, reload cloud info
> new OnReconnect() {
> //implement stuff here
> }
> });
> this ensures that the watchers are persisted across reconnect.
> We need a watch support class to help developers implement watchers correctly
> instead of having some code do it correctly and other code not.
