: Subject: java.lang.Exception: Conflict with StreamingUpdateSolrServer
the fact that you are using StreamingUpdateSolrServer isn't really a
factor here -- what matters is the data you are sending to solr in the
updates...
: location=StreamingUpdateSolrServer line=162 Status for: null is 409
...
: Conflict
A "409" HTTP Status is a "Conflict".
It means that Optimistic concurrency failed. Your update indicated a
document version but the version of hte document on the server didn't meet
the version requirements...
