[druid-user] MAX() in druid is not working

Hey Deepigha,

I guess you mean Calcite’s Druid adapter. I’m not sure what might cause that error, but the Calcite community may be able to help out if nobody on this list has an idea (dev@calcite.apache.org).

Alternatively, that query should work through Druid’s built-in SQL layer, new in Druid 0.10.0: http://druid.io/docs/latest/querying/sql.html
