[jira] [Commented] (SOLR-7785) Segments API returning
java.lang.IllegalStateException
[ https://issues.apache.org/jira/browse/SOLR-7785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14624622#comment-14624622 ]
Upayavira commented on SOLR-7785:
---------------------------------
This is used by the admin UI segments pane. The angular UI has an "auto-refresh" option which is great for watching segments come and go during a bulk update. However, the API sometimes throws an exception.
To reproduce this error, push a constant stream of new content to Solr, then call the API every second. Before long, you will see the exception.
