Based on the stack trace, it looks like the Solr collection create request was not processed (or in-progress) on the overseer node. Can you check if the Solr server hosting the overseer role is healthy and is connected to Zookeeper ?
If there are no issues with the cluster, you can try using the async mode for this operation. https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-AsynchronousCalls Thanks Hrishikesh On Mon, Jan 16, 2017 at 11:36 AM, Joe Obernberger < joseph.obernber...@gmail.com> wrote: > Hi All - trying to create a collection in Solr 6.3.0 on a 5 node cluster > and getting a timeout error.
