Subject [jira] Updated: (PIG-259) allow store to overwrite existing directroy
Date Thu, 25 Feb 2010 07:38:28 GMT

Jeff Zhang updated PIG-259:
---------------------------

    Attachment: Pig_259_2.patch

This patch is for trunk (since LSRD has already been merged into trunk). 

I've put the overwrite logic into StoreFuncInterface. Add two methods 

{code}
public boolean isOverWrite();
    
public void deleteOldOutput(POStore store, PigContext context) throws IOException;
{code}

The second parameter of PigStorage is for overwrite option. It can be 'overwrite' or 'force_write'.
Both is OK.
