Shivaram Venkataraman commented on SPARK-16538:
-----------------------------------------------
So it looks like what is going on is that the `funcName` we get in the case of
`SparkR::createDataFrame` is a list and not a single element. Further the list
contents are [::, SparkR, createDataFrame] - So a change which looks like
{code}
funcName <- as.character(sys.call(sys.parent())[[1]])
if (length(funcName) > 1) {
funcName <- funcName[length(funcName)]
}
{code}
seems to work. [~felixcheung] is there a better way to fix this ?
