[jira] [Commented] (BEAM-1041) IOChannelFactory: supports for
recursively remove().
[ https://issues.apache.org/jira/browse/BEAM-1041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15703677#comment-15703677 ]
Daniel Halperin commented on BEAM-1041:
---------------------------------------
Can this be done entirely IOCF-independently in IOChannelUtils?
> IOChannelFactory: supports for recursively remove().

> 1. FileIOChannelFactory:
> Maybe using deleteDirectory() as suggested in here:
> http://stackoverflow.com/questions/779519/delete-directories-recursively-in-java
> 2. GcsIOChannelFactory:
> Since gcs doesn't have directories, remove recursively means remove all files whose prefixes match.
> However, there are two issues to consider:
> First. remove("gs://mybucket/directory-to-remove")
> a. it should remove "gs://mybucket/directory-to-remove/my-file".
> b. it should not remove "gs://mybucket/directory-to-remove-my-file".
> Second, there should be a way to skip the prefix match for remove(collection-of-a-thousand-files), perhaps by adding a recursive boolean parameter to remove().
