Description

I have a repro using sparklyr but likely to be possible to repro this through c++ bindings:

 

 

library(sparklyr)
library(arrow)

sc <- spark_connect(mater = "local")
DBI::dbGetQuery(sc, "SELECT cast(NULL as bigint)")

Actual:

 

  CAST(NULL AS BIGINT)
1 -4332462841530417152

 

Expected:

  CAST(NULL AS BIGINT)
1                   NA
