[jira] [Commented] (SOLR-11845) OverseerTaskQueue throws Exception
when the response node does not exist
[ https://issues.apache.org/jira/browse/SOLR-11845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16375104#comment-16375104 ]
Varun Thacker commented on SOLR-11845:
--------------------------------------
I think we could do some cleanup's here for better error handling. I'll put out a rough patch shortly.
However do we know a way to trigger this? Or under what circumstances do we see this?
