Shixiong Zhu commented on SPARK-28841:
--------------------------------------
[~srowen] Yep. ":" is not a valid char in a HDFS path. But it's valid for some
other file systems, such as local file system, or S3AFileSystem, and they allow
the user to create such files. I pointed out the codes that hit this issue in
HDFS-14762.
> Spark cannot read a relative path containing ":"

> This is actually a Hadoop issue since the error is thrown from "new
