Subject [jira] Commented: (HIVE-1488) CombineHiveInputFormat for hadoop-19 is broken
Date Mon, 26 Jul 2010 17:49:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12892388#action_12892388
] 

Ning Zhang commented on HIVE-1488:
----------------------------------

It should be removed. The corresponding code in shims 0.20 was removed by fixing HIVE-1317,
but we didn't realized the same code was in 0.19.

> I don't if anyone is using it. After making some recent testing related changes in HIVE-1408,
combine[12].q are no longer working when testing against 19. I have seen them fail earlier
as well and not investigated. Looking at the code, it seems pretty hokey:
> getInputPathsShim():
>       Path[] newPaths = new Path[paths.length];
>       // remove file:                                                               
                                                                          
>       for (int pos = 0; pos < paths.length; pos++) {
>         newPaths[pos] = new Path(paths[pos].toString().substring(5));
>       }
> since we are no longer using 'file:' namespace for test warehouse, this is broke. But
this would be broken against any hdfs instance it would seem(?). Also not clear what we are
trying to do here.
