Subject [jira] Commented: (HIVE-487) Hive does not compile with Hadoop 0.20.0
Date Thu, 23 Jul 2009 18:08:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12734674#action_12734674

Namit Jain commented on HIVE-487:

Overall, it looks good - but can you do a simple cosmetic changes.

1. Have 1 patch instead of different patches for jetty and 487
2. Add more comments:

				29 		 Hadoop 17-19 used Jetty5. Hadoop 20 uses jetty6. Hive still should compile and 
...run with all versions.
				30 		 Java is strongly typed Class based language. The Reflection API is required to 
...circumvent the strong 
				31 		 typing. We have used the reflection API to deal with the known versions of Jetty

...we must work with. 
				32 		 CS students: If you are ever in a debate about classless VS classful programming

...be sure to 
				33 		 reference this code.
				34 		 */

is very good:

Can you repeat a subset of this in HadoopVersion also ?
Hive still should compile and 
...run with all versions. (17-20)

3. usesJobShell: can you add more comments here -- it is true for version 20 but not for 20
4. This may be outside the scope of this - but should some unit tests run for hadoop17, and
some for hadoop 20, as part of ant test.
    Currently, all of them use the default 19. As I mentioned before, this can be done in
a follow-up also.
