Subject [jira] [Updated] (HADOOP-12374) Description of hdfs expunge command is confusing
Date Wed, 02 Sep 2015 06:29:46 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12374?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Weiwei Yang updated HADOOP-12374:
    Release Note:   (was: Usage: hadoop fs -expunge
Empty the Trash. Refer to the HDFS Architecture Guide for more information on the Trash feature.

this description is confusing. It gives user the impression that this command will empty trash,
but actually it only removes old checkpoints. If user sets a pretty long value for fs.trash.interval,
this command will not remove anything until checkpoints exist longer than this value.)
