Hadoop

• ​Cascading - a feature rich API for defining and executing complex, scale-free, and fault tolerant data processing workflows on a Hadoop cluster.

• ​News Flash: Hadoop Development Going Strong @ Yahoo! - 雅虎與微軟的聯盟，難免讓 Hadoop 擁護者擔心小飛象的未來，所以 Hadoop 開發者出來信心喊話了 *^_*

• ​File Appends in HDFS - Tom White 寫的簡介，說明 HDFS 上的檔案擴增(Append)

  ## 早期的 HDFS 不支援 Append，檔案只有當 close 時才寫入。
  
  Early versions of HDFS had no support for an append operation. 
  Once a file was closed, it was immutable and could only be changed by writing a new copy with a different filename.
  A file didn’t exist until it had been successfully closed (by calling FSDataOutputStream’s close() method).
  
  ## 0.19.0 版有支援 HDFS Append File
  
  in July 2008, the append operation was committed in time for the 0.19.0 release of Hadoop Core.
  
  ## 0.19.1 版預設關閉 HDFS Append File, 0.20.0 將 dfs.support.append 預設為不支援
  
  append support was disabled in the 0.19.1 release of Hadoop Core, 
  and in the first release of the 0.20 branch 0.20.0. 
  Configuration parameter dfs.support.append, which is false by default
