Hoss Man updated SOLR-3432:
---------------------------
Attachment: SOLR-3432.test.patch
figured out the problem has to do with the updateLog: if you have the updateLog
enabled, but you do not have a _version_ field, you get no warnings or errors
-- just silently ignored deleteByQuery.
attached patch causes the udpateLog to randomly be enabled in
DirectoUpdateHandlerTest, so with this patch, you should see testBasics() fail
50% of the time.
> deleteByQuery silently ignored unless {{_version_}} field exists in schema
