Hyukjin Kwon commented on SPARK-28040:
--------------------------------------
What does {{glue_data}} return? {{sql}} takes strings so it looks natural.
> 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
> Priority: Major
>
> {{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
