---------------------------------------------
Summary: SolrClient leaks a connection forever when an
unexpected/malformed Entity is received
Key: SOLR-14457
URL: https://issues.apache.org/jira/browse/SOLR-14457
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Affects Versions: 7.7.2
Environment: Solr version: 7.7.2
Solr cloud enabled
Cluster topology: 6 nodes, 1 single collection, 10 shards and 3 replicas. 1
HTTP LB using
Round Robin over all nodes
All cluster nodes have gzip enabled for all paths, all HTTP verbs and all MIME
types.
Solr client: HttpSolrClient targeting the HTTP LB
Reporter: Samuel García Martínez
When the SolrJ receives a malformed response Entity, for example like the one
described in SOLR-14456, the client leaks the connection forever as it's never
released back to the pool.
If Solr (for whatever reason) or any intermediate networking piece (firewall,
proxy, load balancer) messes up the response, SolrJ tries to release the
connection but GzipDecompressingEntity#getContent fails with an
IOException("Not in GZIP format"), making it impossible to release the
connection.
