[jira] [Commented] (SPARK-28841) Spark cannot read a relative path containing ":"

["Sean R. Owen (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-28841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16960460#comment-16960460 ] 

Sean R. Owen commented on SPARK-28841:
--------------------------------------

Yes, that input is ambiguous. You'd have to prefix with "file:" or "hdfs:', etc This isn't a problem with Spark per se but just how anything interpreting input as a potential URI faces.
I can't reproduce your issue [~zsxwing] - that works for me locally (when I fix the ? to :). It happens to work as intended without file: because a scheme can't have a slash.

> Reproducer:
> {code}
> spark.read.parquet("test:test")
> {code}
> Error:
> {code}
> java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: test:test
> {code}
> This is actually a Hadoop issue since the error is thrown from "new Path("test:test")". I'm creating this ticket to see if we can work around this issue in Spark.
