> Hi All
> I am testing TPCx-BB[link title|www.tpc.org/tpcx-bb/default.asp] with the
> code from
> [https://github.com/BigData-Lab-Frankfurt/Big-Data-Benchmark-for-Big-Bench,]
> # The test data are loaded by spark-sql, the parameter
> _spark_.sql._orc_.impl sets to native;
> # During the engine validation power test, when use the different read
> engines that is set _spark_.sql._orc_.impl = hive or _spark_.sql._orc_.impl =
> native, the q22 return different results. When set to hive, the result is
> right, but set to native, less results are returned. Can someone help to find
> why it happens.
> Thanks in advance
