Subject [jira] [Resolved] (HDFS-6921) Add LazyPersist flag to FileStatus
Date Wed, 27 Aug 2014 15:55:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-6921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal resolved HDFS-6921.
---------------------------------

       Resolution: Fixed
    Fix Version/s: HDFS-6581
     Hadoop Flags: Reviewed

[~vinayrpet], correct that we are not serializing the new field but it does seem inconsistent
to have a field we are not writing out. I'll file a Jira to look into removing the field from
{{FileStatus}}.

Committed to the feature branch, thanks for the review all.

> A new flag will be added to FileStatus to indicate that a file can be lazily persisted
to disk i.e. trading reduced durability for better write performance.
