Summary: Fix DOWNNODE -> queue-work explosion
Key: SOLR-10983
URL: https://issues.apache.org/jira/browse/SOLR-10983
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: Scott Blum
Assignee: Scott Blum
Every DOWNNODE command enqueues N copies of itself into queue-work, where N is
number of collections affected by the DOWNNODE.
This rarely matters in practice, because queue-work gets immediately dumped--
however, if anything throws an exception (such as ZK bad version), we don't
clear queue-work. Then the next time through the loop we run the expensive
DOWNNODE command potentially hundreds of times.
