Major Description
There seem to be confusion/inconsistency between contentType (stream or update) parameter as defined in the commented-out update handler and new implicit implementation.
Specifically, in (current 5 build's) techproduct's solrconfig.xml, it says:
<!-- The following are implicitly added
<requestHandler name="/update/json" class="solr.UpdateRequestHandler">
<lst name="defaults">
<str name="stream.contentType">application/json</str>
</lst>
</requestHandler>
<requestHandler name="/update/csv" class="solr.UpdateRequestHandler">
<lst name="defaults">
<str name="stream.contentType">application/csv</str>
</lst>
</requestHandler>
-->
The documentation also says to use stream.contentType at: https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Index+Handlers
However, the http://localhost:8983/solr/techproducts/config says instead:
"/update/json":{
"name":"/update/json",
"class":"org.apache.solr.handler.UpdateRequestHandler",
"defaults":{"update.contentType":"application/json"}},
"/update/csv":{
"name":"/update/csv",
"class":"org.apache.solr.handler.UpdateRequestHandler",
"defaults":{"update.contentType":"application/csv"}},
Seems to be pure inconsistency, since Reference Guide does not mention update.contentType.
Yet earlier in the same solrconfig.xml it says:
To override the request content type and force a specific
Content-type, use the request parameter:
?update.contentType=text/csv
Are these different or same? They should definitely be consistent between code and comment, but it seems there is a bit of an extra confusion on top.
