Description

This is an issue reported by Evgeny Sinelnikov <[e-mail]> in the Spark mailing list:

I'm got a trouble with float type coercion on SparkR with hiveContext.

> result <- sql(hiveContext, "SELECT offset, percentage from data limit > 100")

> show(result)
DataFrame[offset:float, percentage:float]

> head(result)
Error in as.data.frame.default(x[[i]], optional = TRUE) :
cannot coerce class ""jobj"" to a data.frame
