Hello, I am indexing lots of big documents thanks to Solr Cloud in a map reduce job: so every day it is 10000 - 20000 documents (avg:8Mb, max 100Mb, total ~ 100 Gb). This is done is 20 minutes. We have 5 nodes, Solr server is launched with 20 Gb of Ram (and GC1). We add in parallel around 200 SolrDocuments.Unfortunately, Solr Cloud does not accept so much data and it fails (org.apache.solr.client.solrj.SolrServerException: IOException occured when talking to server at:).That still indexed many documents thanks to the multiple attempts, so if I launch multiple times my Map Reduce, I finally get all my documents indexed ... Is there a way to be check availability of Solr Cloud before adding a document or maybe synchronize with the Solr Server ?What do you think ? ThanksBest RegardsBertrand
