Subject [jira] [Commented] (HDFS-3282) Expose getFileLength API.
Date Wed, 18 Apr 2012 03:21:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13256166#comment-13256166
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3282:
----------------------------------------------

Uma, good work!  Some comments:
- Let's put HdfsDataInputStream in org.apache.hadoop.hdfs.client.  It is a package for all
the public APIs.
- HdfsDataInputStream.getAllBlocks() should be public.  You also have to change DFSInputStream.getAllBlocks()
to public.
- Move the @SuppressWarnings("deprecation") annotation on DistributedFileSystem to DistributedFileSystem.reportChecksumFailure(..).
 Otherwise, it will suppress all the warnings in DistributedFileSystem.
- Let's replace the javadoc of DFSDataInputStream with "@deprecated use {@link HdfsDataInputStream}
instead."
