Subject [jira] [Commented] (SPARK-19154) support read and overwrite a same table
Date Wed, 11 Jan 2017 05:17:58 GMT

    [ https://issues.apache.org/jira/browse/SPARK-19154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15817213#comment-15817213

Wenchen Fan commented on SPARK-19154:
-------------------------------------

it turns out that we still remove all the files before overwrite, and there is no easy way
to support this feature unless we overwrite data to a temp directory first. I'm closing this
ticket as "later".

> In SPARK-5746 , we forbid users to read and overwrite a same table. It seems like we
don't need this limitation now, we can remove the check and add regression tests. We may need
to take care of partitioned table though.
