Felix Cheung commented on SPARK-10863:
--------------------------------------
[~olarayej] I"m a little confused - I thought from discussions that for those
complex types we couldn't return R type for, we would return NA? From this test
it looks like it is return the JVM/Scala type instead
{code}
x <- createDataFrame(sqlContext, list(list(as.environment(
list("a"="b", "c"="d", "e"="f")))))
expect_equal(coltypes(x), "map<string,string>")
{code}
This is a little strange since it would neither match simple/atomic types
returned (no 'string') nor match anything in R (no 'map').
