chandra sekhar gunturi commented on HIVE-6363:
----------------------------------------------
I think the issue is resolved by
[HIVE-4194|https://issues.apache.org/jira/browse/HIVE-4194].
The parseURL is called from two places.
https://github.com/apache/hive/blob/trunk/jdbc/src/java/org/apache/hive/jdbc/HiveDriver.java#L233
(from parseURLforPropertyInfo() function)
https://github.com/apache/hive/blob/trunk/jdbc/src/java/org/apache/hive/jdbc/HiveConnection.java#L122
(Constructor of HiveConnection)
Both are having the condition check if(URI.startsWith("jdbc:hive2://"), hence
the parseURL() never gets called when the condition
uri.startsWith(URL_PREFIX) is false.
But it is good to have fix so that if some one calls the function
unconditionally in future, the issue will resurface.
I think [HIVE-4802|https://issues.apache.org/jira/browse/HIVE-4802] did not
affect changes made by
[HIVE-4194|https://issues.apache.org/jira/browse/HIVE-4194] as conditional call
is still in place.
I was testing this on Hive 0.11 & saw the code for parseURL was not changed
from throwing IllegalArgumentException. I think the JIRA can be changed to
lower priority.

> parseURL in the following code is throwing IllegalArgumentException
> http://svn.apache.org/viewvc/hive/trunk/jdbc/src/java/org/apache/hive/jdbc/Utils.java?view=markup
>
> This is going to break other JDBC based connectors because
> java.sql.DriverManager doesn’t catch IllegalArgumentException while probing
> for correct Driver for a given URL.
> A simple test case can have class.forName(org.apache.hive.jdbc.HiveDriver)
> (Loading hiveserver2 JDBC driver) followed by
> class.forName(org.apache.hadoop.hive.jdbc.HiveDriver)(Loading hiveserver JDBC
> driver).
> In this case hiveserver connection will fail with BAD URL format for
> hiveserver. If you reverse the driver loading to hiveserver followed by
> hiveserver2, both the connections will be successful.
> Following code in java.sql.DriverManager is causing the issue
> [[
> // Worker method called by the public getConnection() methods.
> private static Connection getConnection(
> // Walk through the loaded registeredDrivers attempting to make a connection.
> // Remember the first exception that gets raised so we can reraise it.
> for(DriverInfo aDriver : registeredDrivers) {
> // If the caller does not have permission to load the driver then
> // skip it.
> if(isDriverAllowed(aDriver.driver, callerCL)) {
> try {
> Connection con = aDriver.driver.connect(url, info);
> if (con != null) {
> // Success!
> println("getConnection returning " + aDriver.driver.getClass().getName());
> return (con);
> }
> } catch (SQLException ex) {
> if (reason == null) {
> reason = ex;
> }
> }
> } else {
> println(" skipping: " + aDriver.getClass().getName());
> }
> }
> }
> ]]
> Marking it as critical because this is going to restrict consuming JDBC
> driver in production environment where many drivers are loaded on requirement
> rather than statically loading all drivers.
