Cao Manh Dat commented on SOLR-13293:
-------------------------------------
Hi guys,
The problem here happened since in
{{SolrCmdDistributor.Req.getRfFromResponse()}} the {{InputStream}} (passed by
ConcurrentUpdateHttp2SolrClient) had been closed then the client was tried to
fully consume it before closing it.
What are consequences of this problem?
* People get panic about error log like this {{Error consuming and closing http
response stream}}
That is the only problem since {{SolrCmdDistributor.Req.getRfFromResponse}}
already fully consume the request before closing it.
That problem already happens in previous versions of Solr but
{{ConcurrentUpdateSolrClient}} just quietly catch the exception.
My propose for this problem is stopping close() the {{InputStream}} in
{{SolrCmdDistributor.Req.getRfFromResponse}} and note to users that the
InputStream passed by {{ConcurrentUpdateHttp2SolrClient}} should not be closed.
