Hairong Kuang commented on HADOOP-2634:
---------------------------------------
HADOOP-2470 also discussed the unused methods in ClientProtocol. There is one
more method that could be removed: open.
> Hairong has addressed these inconsistencies in HADOOP-2566.
For dfs, I changed the client side to throw a FileNotFoundException. But I did
not change the server side. It would be nice if getFileInfo in namenode also
throw a FileNotFoundException.
> Deprecate exists() and isDir() to simplify ClientProtocol.

> Key: HADOOP-2634
> URL: https://issues.apache.org/jira/browse/HADOOP-2634
> Project: Hadoop
> Issue Type: Improvement
> Components: dfs
> Affects Versions: 0.15.0
> Reporter: Konstantin Shvachko
>
> ClientProtocol can be simplified by removing two methods
> {code}
> public boolean exists(String src) throws IOException;
> public boolean isDir(String src) throws IOException;
> {code}
> This is a redundant api, which can be implemented in DFSClient as convenience
> methods using
> {code}
> public DFSFileInfo getFileInfo(String src) throws IOException;
> {code}
> Note that we already deprecated several Filesystem method and advised to use
> getFileStatus() instead.
> Should we deprecate them in 0.16?
