spark_apply() error, "Can't query fields"

[Brian Stamper]

Attempting to use spark_apply but getting an error. This is on a Cloudera Machine Learning environment, with the same error appearing in either Spark 2.4.7 or 3.2.1. On another machine with a local Spark install I do not see this issue, but the error I'm getting here is not giving much indication what the problem is.

For a small demo I'll use the first spark_apply() example from sparklyr - Distributing R Computations

library(tidyverse)
library(sparklyr)

conf <- spark_config()
sc <- spark_connect(master = 'yarn-client', config = conf)

sdf_len(sc, 5, repartition = 1) %>%
  spark_apply(function(e) I(e))

And the error I get looks like the following. It does make me wonder if this is actually a dbplyr issue instead.

Error in `db_query_fields.DBIConnection()`:
! Can't query fields.
Caused by error in `value[[3L]]()`:
!
