Jason Gerlowski updated SOLR-8266:
----------------------------------
Attachment: SOLR-8266.patch
Making the first two changes Joel laid out (StreamHandler and ParallelStream)
seemed easy.
I'm having a little more trouble with the third piece of this patch- tweaking
StreamingTest's use of parallel streams to use a properly configured
StreamFactory/StreamContext.
The current patch gets through several of the parallel-stream tests, before
hitting {{testParallelEOF}} and failing with the follow stack trace:
{code}
java.io.IOException: java.util.concurrent.ExecutionException:
java.io.IOException: --> https://127.0.0.1:35540/collection1/:Invalid stream
expression count(merge(search(collection1,q="id:(4 1 8 7
9)",fl="id,a_s,a_i",sort="a_i
asc",partitionKeys=a_i,zkHost="127.0.0.1:36053/solr"),search(collection1,q="id:(0
2 3 6)",fl="id,a_s,a_i",sort="a_i
asc",partitionKeys=a_i,zkHost="127.0.0.1:36053/solr"),on="a_i asc")) - function
'count' is unknown (not mapped to a valid TupleStream)

I've still got some investigation to do here; probably just overlooking
something simple. But it's late here, and I'd like to upload my progress so I
can continue from a different computer in the morning. (And if anyone chimes
in with thoughts/advice, all the better).
