             Summary: sql() fails to process output of glue::glue_data()
                 Key: SPARK-28040
                 URL: https://issues.apache.org/jira/browse/SPARK-28040
             Project: Spark
          Issue Type: Bug
          Components: R
    Affects Versions: 2.4.3
            Reporter: Michael Chirico


{{glue}} package is quite natural for sending parameterized queries to Spark from R. Very similar to Python's {{format}} for strings. Error is as simple as
{code:java}
library(glue)
library(sparkR)
sparkR.session()

query = glue_data(list(val = 4), 'select {val}')
sql(query){code}
Error in writeType(con, serdeType) : 
  Unsupported type for serialization glue
{{sql(as.character(query))}} works as expected but this is a bit awkward / post-hoc
