Jeff Zhang commented on PIG-259:
--------------------------------
Response to Alan regarding his comments,
1. I put the logic of deleting output file in JobControlCompiler, then it is
easy for me to delay the deletion util the dependent job is done.
2. I prefer using keywords rather than string, because if using string, the
following statement: {code} store a into 'output' 'overwrite'; {code} has two
consecutive string, it looks a little weird in my opinion.
3. I think the semantic of overwrite is the same as it is in file system. In
file system, when we overwrite file using java api, it won't complain even the
file does not exist
> allow store to overwrite existing directroy
