Hello, I was looking into the code to try to get to the root of this issue. Looks like this is an issue after all (as of 7.2.1 which is the version we are using), but wanted to confirm on the user list before creating a JIRA. I found that the soTimeout property of ConcurrentUpdateSolrClient class (in the code referenced below) remains null and hence the default of 600000 ms is set as the timeout in HttpPost class instance variable "method". https://github.com/apache/lucene-solr/blob/e6f6f352cfc30517235822b3deed83df1ee144c6/solr/solrj/src/java/org/apache/solr/client/solrj/impl/ConcurrentUpdateSolrClient.java#L334
When the call is finally made in the below line, the Httpclient does contain the configured timeout (as in solr.xml or -DdistribUpdateSoTimeout) but gets overriden by the hard default of 600000 in the "method" parameter of the execute call. https://github.com/apache/lucene-solr/blob/e6f6f352cfc30517235822b3deed83df1ee144c6/solr/solrj/src/java/org/apache/solr/client/solrj/impl/ConcurrentUpdateSolrClient.java#L348 The hard default of 600000 is set here: https://github.com/apache/lucene-solr/blob/e6f6f352cfc30517235822b3deed83df1ee144c6/solr/solrj/src/java/org/apache/solr/client/solrj/impl/ConcurrentUpdateSolrClient.java#L333 I tried to create a local patch with the below fix which works fine: https://github.com/apache/lucene-solr/blob/86fe24cbef238d2042d68494bd94e2362a2d996e/solr/core/src/java/org/apache/solr/update/StreamingSolrClients.java#L69 client = new ErrorReportingConcurrentUpdateSolrClient.Builder(url, req, errors) .withHttpClient(httpClient) .withQueueSize(100) .withSocketTimeout(getSocketTimeout(req)) .withThreadCount(runnerCount) .withExecutorService(updateExecutor) .alwaysStreamDeletes() .build(); private int getSocketTimeout(SolrCmdDistributor.Req req) { if(req==null) { return UpdateShardHandlerConfig.DEFAULT_DISTRIBUPDATESOTIMEOUT; } return req.cmd.req.getCore().getCoreContainer().getConfig().getUpdateShardHandlerConfig().getDistributedSocketTimeout(); } I found this open JIRA on this issue: https://issues.apache.org/jira/browse/SOLR-12550?jql=text%20~%20%22distribUpdateSoTimeout%22 Should I update the JIRA with this ?
