[jira] Commented: (HADOOP-3177) Expose DFSOutputStream.fsync API though the FileSystem interface

    [ https://issues.apache.org/jira/browse/HADOOP-3177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12592851#action_12592851 ] 

Tsz Wo (Nicholas), SZE commented on HADOOP-3177:
------------------------------------------------

Do we really need to add this method to the FileSystem API?  fsync seems DFS specific.

> In the current code, there is a DFSOutputStream.fsync() API that allows a client to flush all buffered data to the datanodes and also persist block locations on the namenode. This API should be exposed through the generic API in the org.hadoop.fs.
