> When test on DSE portfolio demo, which basically creates a few C* tables and inserts some data into the tables, then run some Hive queries on the tables.
> I attach the Hive queries
> After some queries are done, C* node is dead on native port, cqlsh can't login any more.
> Some thread dumps are attached. Too many threads are in waiting mode and system is not responding.
