Subject Re: Exporting data using solr streaming expressions is randomly not working
Date Thu, 27 Sep 2018 17:32:22 GMT
That is weird, I've not encountered this behavior. There has been some
changes in 7.4 to the export handler, and I'm wondering if a bug was
introduced. The stack trace you are posting is coming from the node where
the expression is being run. Can you check the logs from the shards to see
if there are errors on the shards?
