Subject [jira] Commented: (PIG-259) allow store to overwrite existing directroy
Date Fri, 05 Feb 2010 07:00:30 GMT

    [ https://issues.apache.org/jira/browse/PIG-259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829981#action_12829981

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
