Subject Re: Parallel SQL Interface returns "java.lang.NullPointerException" after reloading collection
Date Sun, 01 May 2016 17:05:02 GMT
Can you post your stack trace? I suspect this has to do with how the
Streaming API is interacting with SolrCloud. We can probably also create a
jira ticket for this.
