Deneche A. Hakim updated DRILL-1912:

Description:
Window functions below are currently:
* Supported in Calcite
* Not supported in DRILL
* Not documented in DRILL documentation
ROW_NUMBER()
FIRST_VALUE()
LAST_VALUE()
PERCENT_RANK()
DENSE_RANK()

1.0 release. Therefore, for 0.8.0 release we are going to throw "Unsupported"
error message for these functions as well as for every other function that

DRILL-1487 - window functions return wrong result
DRILL-1908 - new implementation of window functions
Assigning to Jacques on his request, targeting 0.8.0
