Subject [jira] [Updated] (HDFS-5537) Remove FileWithSnapshot interface
Date Wed, 20 Nov 2013 22:35:35 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5537?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jing Zhao updated HDFS-5537:

    Attachment: HDFS-5537.000.patch

Initial patch depending on HDFS-5285. Some implementation in INodeFile now can be moved to
INodeFileWithSnapshot, but since we will remove INodeFileWithSnapshot and replace it a Snapshot
feature, currently I just leave these code in INodeFile.java.

> We use the FileWithSnapshot interface to define a set of methods shared by INodeFileWithSnapshot
and INodeFileUnderConstructionWithSnapshot. After using the Under-Construction feature to
replace the INodeFileUC and INodeFileUCWithSnapshot, we no longer need this interface.
