> 30-node setup has TPC-H Drill (SF100) and TPC-DS Drill (SF100) in two different workspaces.
> TPC-H Query 6 is executed on the cluster successfully, followed by execution of TPC-DS
Query 2; which hangs during the executeQuery() operation. After a 2min timeout, the TPC-H
Query is executed on the cluster, but this also hangs during the fetching of rows from the
ResultSet. The profile page for the second attempt at TPC-H query 6 shows it as pending.
> The TPC-H schema is in its own workspace which exposes the directories as tables.
> The TPC-DS schema is in its own workspace, which has views on top of the directories
containing the actual tables' data.
