I think that in version 4.7.2 streaming is disabled by default and you have to enable it in file solrconfig.xml
change
<requestParsers enableRemoteStreaming="false"
to
<requestParsers enableRemoteStreaming="true"
Also, have a look at the documentation
http://wiki.apache.org/solr/SolrSecurity#Streaming_Consideration
Let me know if this fixed the issue. Be aware of security when enabling remote streaming.
