Description:
Given an external table definition where the data consists of many CSV files,
{{input_file_name()}} returns empty strings.
Table definition:

WITH SERDEPROPERTIES (
"separatorChar" = ",",
"quoteChar" = "\"",
"escapeChar" = "\\"
)
LOCATION 'file:///Users/sim/spark/test/external_test'
{code}
Query:
{code}
sql("SELECT input_file_name() as file FROM external_test").show
{code}
Output:
{code}
