You'll have to use StackOverflow or DataStax for support on DSE Search. It looks like you have a Field Output Transformer ( *UserFieldOutputTransformer.java*). The NPE might be related to processing that occurs there - try removing this FOT and see if the NPE still occurs. For example, maybe the FOT is setting an output column value to NULL.
Also, see if there is a "Caused By" entry elsewhere in the Java stack trace. -- Jack Krupansky On Tue, Apr 12, 2016 at 6:07 AM, Joseph Tech <jaalex.t...@gmail.com> wrote: > hi, > > I am facing an issue where Solr queries executed from cqlsh using the > solr_query field is throwing an NPE in system.log, while cqlsh shows the > following error: > > Unable to complete request: one or more nodes were unavailable. > > These queries work fine thru the Solr admin console UI. > > Below is the stacktrace when executing the wildcard query : > > select * from user where solr_query='user_id:*ABCD-**'; > > The line in bold (from custom Output FT) shows that the key corresponding > to ABCD-* was identified, but results are not returned.
