方法详细资料

initialize

public void initialize(URI name,
              Configuration conf)
                throws IOException

从类复制的说明: FileSystem

Called after a new FileSystem instance is constructed.

覆盖:

initialize 在类中 HftpFileSystem

参数:

name - a uri whose authority section names the host, port, etc. for this FileSystem

conf - the configuration

抛出:

IOException

getDefaultPort

protected int getDefaultPort()

从类复制的说明: FileSystem

Get the default port for this file system.

覆盖:

getDefaultPort 在类中 HftpFileSystem

返回:

the default port or 0 if there isn't one

getUnderlyingProtocol

protected String getUnderlyingProtocol()

Return the underlying protocol that is used to talk to the namenode.

覆盖:

getUnderlyingProtocol 在类中 HftpFileSystem

openConnection

protected HttpURLConnection openConnection(String path,
                               String query)
                                    throws IOException

从类复制的说明: HftpFileSystem

Open an HTTP connection to the namenode to read file data and metadata.

覆盖:

openConnection 在类中 HftpFileSystem

参数:

path - The path component of the URL

query - The query component of the URL

抛出:
