Key: SOLR-5719
URL: https://issues.apache.org/jira/browse/SOLR-5719
Project: Solr
Issue Type: Bug
Components: clients - java
Affects Versions: 4.6.1
Environment: 2 ZooKepper Servers, 4 SolrServers, JDK 1.7 on Jetty
CentOS 6.4
1 Core (collection1) with two shards which have 2 instances each one
Reporter: Allan Baliberdin
CloudSolrServer instance on the client side put its threads on waiting mode
when shard goes down, and never wake up them.
Teste code:
...
CloudSolrServer server = new
CloudSolrServer("172.16.199.106:8080,172.16.198.198:8080",false);
server.setDefaultCollection("collection1");
for(int i=0; i< 10000; i++){
SolrInputDocument doc = new SolrInputDocument();
doc.addField("id", i);
doc.addField("title", i+" - Document test");
doc.addField("content", i+" - Test Content");
server.add(doc);
}
...
During this test we put the shard #1 down, just for check fault tolerance. And

But not throw this exception through my main Thread, and lock loop.
After we starts up shard #1 CloudSolrServer (client side) could not return from
failure.
Then my program never exit, and CloudSolrServer could not be reused.
