Hi guys, I deployed BlinkDB(built atop Shark) and running Spark 0.9. I tried to run several TPCDS shark queries taken from https://github.com/cloudera/impala-tpcds-kit/tree/master/queries-sql92-modified/queries/shark. However, the following exceptions are encountered. Do you have any idea why that might happen ?
