----------------------------
Summary: During concurrency some Solr document are not seen even
after soft and hard commit
Key: SOLR-9466
URL: https://issues.apache.org/jira/browse/SOLR-9466
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Affects Versions: 4.10.2
Environment: Cent OS
Reporter: Ganesh
Priority: Critical
Solr cloud with 2 nodes, master master, with 5 collection and 2 shards in each
collection.
During concurrent usage of SOLR where both updates and search is sent to SOLR
server, some of our updates / adding of new documents are getting lost.
We could see that update hitting solr and we could see it in localhost_access
file of tomcat, also in catalina.out. But still we couldn't see that record
while searching.
Following is the catalina.out logs for the document which is getting indexed
properly.
