Multithread update client causes exceptions and dropped documents
-----------------------------------------------------------------
Key: SOLR-360
URL: https://issues.apache.org/jira/browse/SOLR-360
Project: Solr
Issue Type: Bug
Components: update
Affects Versions: 1.3
Environment: test fails on both pc + mac, tomcat + jetty all java 1.6
Reporter: Will Johnson
we were doing some performance testing for the updating aspects of solr and ran
into what seems to be a large problem. we're creating small documents with an
id and one field of 1 term only submitting them in batches of 200 with commits
every 5000 docs. when we run the client with 1 thread everything is fine.
when we run it win >1 threads things go south (stack trace is below). i've
attached the junit test which shows the problem. this happens on both a mac
and a pc and when running solr in both jetty and tomcat. i'll create a junit
issue if necessary but i thought i'd see if anyone else had run into this
problem first.
also, the problem does not seem to surface under solr1.2
(RyanM suggested it might be related to SOLR-215)
