[jira] [Commented] (OOZIE-3548) FS EL action to compute size of glob

    [ https://issues.apache.org/jira/browse/OOZIE-3548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16962547#comment-16962547 ]

-------------------------------------------

Would suggest https://github.com/apache/pig/blob/trunk/src/org/apache/pig/LoadFunc.java#L230-L250 instead

> There is an FS el function (dirSize) that computes the size of a single directory. 
>  
> It would be helpful if oozie could give the size of a list or glob of directories (for example, to get the total size of an input dependency with multiple paths).
>  
> I'd like to use this to compute a parallelism value in Pig. Pig sort of supports this with the bytesPerReducer setting but that settings is applied to the entire job; I'd like more flexibility.
>  
> Unfortunately, correctly supporting both a list of filese (as provided by oozie) and globs requires copying in this method:

> [~rohini] [~puru] I am happy to submit a patch. Any suggestions before I do so?
