> Implement bulk delete command as hadoop fs command operation
> -------------------------------------------------------------
>
> Key: HADOOP-19254
> URL: https://issues.apache.org/jira/browse/HADOOP-19254
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 3.4.1
> Reporter: Mukund Thakur
> Assignee: Harshit Gupta
> Priority: Major
> Labels: pull-request-available
>
> {code}
> hadoop fs -bulkdelete <base-url> <file>
> {code}
> Key uses
> * QE: Testing from python and other scripting languages
> * cluster maintenance: actual bulk deletion operations from the store
> one thought there: we MUST qualify paths with / elements: if a passed in path
> ends in /, it means "delete a marker", not "delete a dir"'. and if it doesn't
> have one then it's an object.. This makes it possible to be used to delete
> surplus markers or where there is a file above another file...cloudstore
> listobjects finds this
