[jira] [Commented] (SOLR-13591) AlreadyClosedException in SolrJ
[ https://issues.apache.org/jira/browse/SOLR-13591?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17412124#comment-17412124 ]
Murray Johnston commented on SOLR-13591:
----------------------------------------
FWIW, we traced our occurrences of this issue to us inappropriately calling ZkClientClusterStateProvider.close(). In earlier versions of the client the class would reinitialize if the connection was broken but the newer version (properly, in my opinion) refuses to do so and throws the AlreadyClosedException. So this is likely not a bug but a misuse.
