[云计算]Alluxio源码分析:RPC框架浅析(一)


        Alluxio源码分析是一个基于内存的分布式文件系统,和HDFS、HBase等一样,也是由主从节点构成的。而节点之间的通信,一般都是采用的RPC通讯模型。Alluxio中RPC是基于何种技术如何实现的呢?它对于RPC请求是如何处理的?都涉及到哪些组件?本文将针对这些问题,为您一一解答。
        一、Alluxio中RPC实现技术支持
        Alluxio中的RPC是依靠Thrift实现的,Apache Thrift 是 Facebook 实现的一种高效的、支持多种编程语言的远程服务调用的框架。它采用接口描述语言定义并创建服务,支持可扩展的跨语言服务开发,所包含的代码生成引擎可以在多种语言中,如 C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk 等创建高效的、无缝的服务,其传输数据采用二进制格式,相对 XML 和 JSON 体积更小,对于高并发、大数据量和多语言的环境更有优势。
        具体关于Thrift的介绍,请参照《Thrift简介》一文。
        二、Alluxio中RPC实现细节
        在《Thrift开发示例》一文中,我们已经详细讲解了如何利用Java语言开发一个Thrift程序。下面,对比着《Thrift开发示例》一文中的示例,我们看下Alluxio中的RPC服务是如何实现的。
        1、服务接口脚本文件file_system_master.thrift
        在file_system_master.thrift文件中,定义了Alluxio中文件系统相关的Master服务接口,具体如下:
        (1)定义了命名空间为java alluxio.thrift
java alluxio.thrift
        (2)定义了一些服务中需要用到的结构体,如文件信息FileInfo、完成文件选项CompleteFileTOptions、创建文件选项CreateFileTOptions等,具体如下:
/**
 * 完成文件选项
 */
struct CompleteFileTOptions {
  1: optional i64 ufsLength
}

/**
 * 创建目录选项
 */
struct CreateDirectoryTOptions {
  1: optional bool persisted
  2: optional bool recursive
  3: optional bool allowExists
}

/**
 * 创建文件选项
 */
struct CreateFileTOptions {
  1: optional i64 blockSizeBytes
  2: optional bool persisted
  3: optional bool recursive
  4: optional i64 ttl
}

/**
 * 挂载选项
 */
struct MountTOptions {
  1: optional bool readOnly
}

/**
 * 文件信息
 */
struct FileInfo {
  1: i64 fileId
  2: string name
  3: string path
  4: string ufsPath
  5: i64 length
  6: i64 blockSizeBytes
  7: i64 creationTimeMs
  8: bool completed
  9: bool folder
  10: bool pinned
  11: bool cacheable
  12: bool persisted
  13: list<i64> blockIds
  15: i32 inMemoryPercentage
  16: i64 lastModificationTimeMs
  17: i64 ttl
  18: string userName
  19: string groupName
  20: i32 permission
  21: string persistenceState
  22: bool mountPoint
}

/**
 * 文件系统命令
 */
struct FileSystemCommand {
  1: common.CommandType commandType
  2: FileSystemCommandOptions commandOptions
}

/**
 * 持久化命令选项
 */
struct PersistCommandOptions {
  1: list<PersistFile> persistFiles
}

/**
 * 持久化文件
 */
struct PersistFile {
  1: i64 fileId
  2: list<i64> blockIds
}

/**
 * 设置属性选项
 */
struct SetAttributeTOptions {
  1: optional bool pinned
  2: optional i64 ttl
  3: optional bool persisted
  4: optional string owner
  5: optional string group
  6: optional i16 permission
  7: optional bool recursive
}

/**
 * 文件系统命令行选项
 */
union FileSystemCommandOptions {
  1: optional PersistCommandOptions persistOptions
}
        (3)定义了文件系统的两个服务,一个是Client至Master的FileSystemMasterClientService,另外一个是Worker至Master的FileSystemMasterWorkerService,其中FileSystemMasterClientService定义了读写文件等需要的createFile()、createDirectory()、completeFile()、getStatus()、getUfsAddress()、loadMetadata()、mount()等客户端Client至主节点Master通信的重要方法,而FileSystemMasterWorkerService定义了心跳等需要的getFileInfo()、heartbeat()等从节点Worker至主节点Master通信的重要方法,具体如下:
/**
 * This interface contains file system master service endpoints for Alluxio clients.
 */
service FileSystemMasterClientService extends common.AlluxioService {

  /**
   * Marks a file as completed.
   * 标记一个文件完成
   */
  void completeFile( /** the path of the file */ 1: string path,
      /** the method options */ 2: CompleteFileTOptions options)
    throws (1: exception.AlluxioTException e)

  /**
   * Creates a directory.
   * 创建一个目录
   */
  void createDirectory( /** the path of the directory */ 1: string path,
      /** the method options */ 2: CreateDirectoryTOptions options)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)

  /**
   * Creates a file.
   * 创建一个文件
   */
  void createFile( /** the path of the file */ 1: string path,
      /** the options for creating the file */ 2: CreateFileTOptions options)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)

  /**
   * Frees the given file or directory from Alluxio.
   * 从Alluxio中释放指定文件或目录 
   */
  void free( /** the path of the file or directory */ 1: string path,
      /** whether to free recursively */ 2: bool recursive)
    throws (1: exception.AlluxioTException e)

  /**
   * Returns the list of file blocks information for the given file.
   * 获取指定文件对应的文件块信息列表
   */
  list<common.FileBlockInfo> getFileBlockInfoList( /** the path of the file */ 1: string path)
    throws (1: exception.AlluxioTException e)

  /**
   * Returns the status of the file or directory.
   * 返回指定文件或目录的状态信息
   */
  FileInfo getStatus( /** the path of the file or directory */ 1: string path)
    throws (1: exception.AlluxioTException e)

  /**
   * Returns the status of the file or directory, only used internally by servers.
   * 返回指定文件或目录的状态信息,仅服务端内部使用
   */
  FileInfo getStatusInternal( /** the id of the file or directory */ 1: i64 fileId)
    throws (1: exception.AlluxioTException e)

  /**
   * Generates a new block id for the given file.
   * 为给定文件生成一个新的数据块ID
   */
  i64 getNewBlockIdForFile( /** the path of the file */ 1: string path)
    throws (1: exception.AlluxioTException e)

  /**
   * Returns the UFS address of the root mount point.
   * 获取根挂载点对应底层文件系统地址
   *
   * THIS METHOD IS DEPRECATED SINCE VERSION 1.1 AND WILL BE REMOVED IN VERSION 2.0.
   */
  string getUfsAddress()

  /**
   * If the path points to a file, the method returns a singleton with its file information.
   * If the path points to a directory, the method returns a list with file information for the
   * directory contents.
   */
  list<FileInfo> listStatus( /** the path of the file or directory */ 1: string path)
    throws (1: exception.AlluxioTException e)

  /**
   * Loads metadata for the object identified by the given Alluxio path from UFS into Alluxio.
   */
  // TODO(jiri): Get rid of this.
  i64 loadMetadata( /** the path of the under file system */ 1: string ufsPath,
      /** whether to load meta data recursively */ 2: bool recursive)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)

  /**
   * Creates a new "mount point", mounts the given UFS path in the Alluxio namespace at the given
   * path. The path should not exist and should not be nested under any existing mount point.
   */
  void mount( /** the path of alluxio mount point */ 1: string alluxioPath,
      /** the path of the under file system */ 2: string ufsPath,
      /** the options for creating the mount point */ 3: MountTOptions options)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)

  /**
   * Deletes a file or a directory and returns whether the remove operation succeeded.
   * NOTE: Unfortunately, the method cannot be called "delete" as that is a reserved Thrift keyword.
   */
  void remove( /** the path of the file or directory */ 1: string path,
      /** whether to remove recursively */ 2: bool recursive)
    throws (1: exception.AlluxioTException e)

  /**
   * Renames a file or a directory.
   */
  void rename( /** the path of the file or directory */ 1: string path,
      /** the desinationpath of the file */ 2: string dstPath)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)

  /**
   * Sets file or directory attributes.
   */
  void setAttribute( /** the path of the file or directory */ 1: string path,
       /** the method options */ 2: SetAttributeTOptions options)
    throws (1: exception.AlluxioTException e)

  /**
   * Schedules async persistence.
   */
  void scheduleAsyncPersist( /** the path of the file */ 1: string path)
    throws (1: exception.AlluxioTException e)

  /**
   * Deletes an existing "mount point", voiding the Alluxio namespace at the given path. The path
   * should correspond to an existing mount point. Any files in its subtree that are backed by UFS
   * will be persisted before they are removed from the Alluxio namespace.
   */
  void unmount( /** the path of the alluxio mount point */ 1: string alluxioPath)
    throws (1: exception.AlluxioTException e, 2: exception.ThriftIOException ioe)
}

/**
 * This interface contains file system master service endpoints for Alluxio workers.
 */
service FileSystemMasterWorkerService extends common.AlluxioService {

  /*
   * Returns the file information.
   */
  FileInfo getFileInfo( /** the id of the file */ 1: i64 fileId)
    throws (1: exception.AlluxioTException e)

  /**
   * Returns the set of pinned files.
   */
  set<i64> getPinIdList()

  /**
   * Periodic file system worker heartbeat. Returns the command for persisting
   * the blocks of a file.
   */
  FileSystemCommand heartbeat( /** the id of the worker */ 1: i64 workerId,
      /** the list of persisted files */ 2: list<i64> persistedFiles)
    throws (1: exception.AlluxioTException e)
}
        2、根据服务接口脚本文件file_system_master.thrift中service生成的Java类,包括FileSystemMasterClientService.java、FileSystemMasterWorkerService.java,其中分别包含Thrift特有的Iface、Processor等接口或类,完整代码如下:
