Subject [jira] Commented: (HDFS-1179) Implement a file change log
Date Fri, 04 Jun 2010 05:10:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12875484#action_12875484

dhruba borthakur commented on HDFS-1179:

I agree with the above comments that this is similar to the audit log facility. is there a
way to make the audit logging happen directly to a HDFS file (in the same HDFS cluster)?

> The File Change Log (FCL) is a construct that records all metadata changes in a file
system (http://en.wikipedia.org/wiki/File_change_log). This JIRA is to discuss various high-level
approaches to implementing such a FCL for HDFS.
