[jira] Updated: (PIG-569) Inconsistency with Hadoop in Pig load
statements involving globs with subdirectories
[ https://issues.apache.org/jira/browse/PIG-569?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kevin Weil updated PIG-569:
---------------------------
Environment: FC Linux x86/64, Pig revision 724576 (was: FC Linux x86/64)
> Inconsistency with Hadoop in Pig load statements involving globs with subdirectories
> ------------------------------------------------------------------------------------
>
> Key: PIG-569
> URL: https://issues.apache.org/jira/browse/PIG-569
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: types_branch
> Environment: FC Linux x86/64, Pig revision 724576
> Reporter: Kevin Weil
> Fix For: types_branch
>
>
> Pig cannot handle LOAD statements with Hadoop globs where the globs have subdirectories. For example,
> A = LOAD 'dir/{dir1/subdir1,dir2/subdir2,dir3/subdir3}' USING ...
> A similar statement in Hadoop, hadoop dfs -ls dir/{dir1/subdir1,dir2/subdir2,dir3/subdir3}, does work correctly.
> The output of running the above load statement in pig, built from svn revision 724576, is:
