Hello Driller,
I'm facing issues using the Filter function of Tableau with Drill : Tableau
always populates values of the filter with "null".The action is translated into
2 queries within Drill :
SELECT * FROM (SELECT field FROM Table GROUP BY field ORDER BY field ASC) T
LIMIT 0
SELECT field FROM Table GROUP BY field ORDER BY field ASC
It seems that Tableau is fetching the result of the first query (null - which
seems to by generated to catch exceptions) instead of the second one.
Anyone already met this issue ? Is there a workaround or customization
parameter to ajust ?
conf : Tableau v9.0 + MapRDrillODBC driver with TDC file deployedDrill V1.1.0
