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?
