[jira] [Updated] (SPARK-29969) parse_url function result in
incorrect result
[ https://issues.apache.org/jira/browse/SPARK-29969?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon updated SPARK-29969:
---------------------------------
Description:
In this Jira using java.net.URI instead of java.net.URL for performance reason.
https://issues.apache.org/jira/browse/SPARK-16826
However, in the case of some unconventional parameters, it can lead to incorrect results.
For example, when the URL is encoded, the function cannot resolve the correct result.
{code}
0: jdbc:hive2://localhost:10000> SELECT parse_url('http://uzzf.down.gsxzq.com/download/%E5%B8%B8%E7%94%A8%E9%98%80%E9%97%A8CAD%E5%9B%BE%E7%BA%B8%E5%A4%', 'HOST');

Here's a similar problem.

Our team used the spark function to run data for months, but now we have to run it again.
It's just too painful.:(:(:(
