Subject [jira] [Commented] (HDFS-5916) provide API to bulk delete directories/files
Date Mon, 10 Feb 2014 03:56:19 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13896195#comment-13896195
] 

Sergey Shelukhin commented on HDFS-5916:
----------------------------------------

I mean the programmatic API (e.g. on FileSystem class) for an arbitrary list of directories
(which have common parent sub-tree in these cases, but don't have to I guess).
i.e. List<Path> dirList = ...; FileSystem fs = ...; fs.deleteAll(dirList);

> provide API to bulk delete directories/files

> It would be nice to have an API to delete directories and files in bulk - for example,
when deleting Hive partitions or HBase regions in large numbers, the code could avoid many
trips to NN.
