Hyukjin Kwon updated SPARK-27346:
---------------------------------
Description:
I haven't tested by myself on Windows and I am not 100% sure if this is going
to cause an actual problem.
The codes here:
{code}
assert examples.isEmpty() || examples.startsWith(System.lineSeparator()
+ " Examples:");
{code}
Given my speculation, if Spark is built in Linux, and it's executed on Windows,
it looks possible to throw an exception because encoded newline in the binary
is {{\n}} but {{System.lineSeparator}} returns {{\r\n}}.
I haven't tested it by myself but I think it's better to loosen the condition
and forget about this problem.
