[jira] [Created] (SOLR-12978) Autoscaling Suggester tries to test
metrics for dead nodes
Shalin Shekhar Mangar created SOLR-12978:
--------------------------------------------
Summary: Autoscaling Suggester tries to test metrics for dead nodes
Key: SOLR-12978
URL: https://issues.apache.org/jira/browse/SOLR-12978
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: AutoScaling, SolrCloud
Reporter: Shalin Shekhar Mangar
Fix For: 7.6, master (8.0)
Suggester tries to test clauses in the applyRules phase for each row regardless of whether the row is live or not. When the node is not live and there are no metrics fetched, testing the clause causes an NPE.
