> -------------------------------------------------------------------
>
> Key: SPARK-33113
> URL: https://issues.apache.org/jira/browse/SPARK-33113
> Project: Spark
> Issue Type: Bug
> Components: R
> Affects Versions: 3.0.0, 3.0.1
> Reporter: Jacek Pliszka
> Priority: Major
>
> Running in databricks on Azure
> library("arrow")
> library("SparkR")
> df <- as.DataFrame(list("A", "B", "C"), schema="ColumnA")
> udf <- function(key, x) data.frame(out=c("dfs"), stringAsFactors=FALSE)
>
> This works:
> sparkR.session(master = "local[*]", sparkConfig=list(spark.sql.execution.arrow.sparkr.enabled = "false"))
> df1 <- gapply(df, c("ColumnA"), udf, "out String")
> collect(df1)
> This fails:
> sparkR.session(master = "local[*]", sparkConfig=list(spark.sql.execution.arrow.sparkr.enabled = "true"))
> df2 <- gapply(df, c("ColumnA"), udf, "out String")
> collect(df2)
>
> with error
> {{ Error in readBin(con, raw(), as.integer(dataLen), endian = "big") : }}Error in readBin(con, raw(), as.integer(dataLen), endian = "big") : invalid 'n' argument
> Error in readBin(con, raw(), as.integer(dataLen), endian = "big") : invalid 'n' argument In addition: Warning messages: 1: Use 'read_ipc_stream' or 'read_feather' instead. 2: Use 'read_ipc_stream' or 'read_feather' instead.
