Goutam Mandal commented on SOLR-10487:
--------------------------------------

[~elyograg], thanks for helping with building the HttpClient :) Also replacing 
HttpClient reference with CloseableHttpClient gave a cleaner approach. Did away 
with the unnecessary typecasting.

QUERY_TIMEOUT is supposed to take precedence over TIMEOUT attribute. Did not 
remove TIMEOUT as it would affect upgrading from older version. Missed the 
changes while merging from Solr 6 branch (my cluster runs on Solr 6.2). 

Incorporated above changes in the attached patch. Also pushed to forked repo.

> This issue pertains to SolrEntityProcessor for importing documents from one 
> Solr to another over HTTP. There have been instances when the 
> DataImportHandler (DIH) hangs due to network/LB level issues. The abort 
> command fails to stop the in-progress frozen import process. The DIH remains 
> in this state for days and does not accept new request for import until Solr 
> restart. The current implementation of SolrEntityProcessor has timeout at 
> query level only.
> There should be option to specify connection as well as socket read timeouts. 
> The import process must fail in case of any anomaly and not remain in hung 
> state.
