| 13 | ## 早期的 HDFS 不支援 Append,檔案只有當 close 時才寫入。 |
| 14 | |
| 15 | Early versions of HDFS had no support for an append operation. |
| 16 | Once a file was closed, it was immutable and could only be changed by writing a new copy with a different filename. |
| 17 | A file didn’t exist until it had been successfully closed (by calling FSDataOutputStream’s close() method). |
| 18 | |
| 19 | ## 0.19.0 版有支援 HDFS Append File |
| 20 | |
| 21 | in July 2008, the append operation was committed in time for the 0.19.0 release of Hadoop Core. |
| 22 | |
| 23 | ## 0.19.1 版預設關閉 HDFS Append File, 0.20.0 將 dfs.support.append 預設為不支援 |
| 24 | |
| 25 | append support was disabled in the 0.19.1 release of Hadoop Core, |
| 26 | and in the first release of the 0.20 branch 0.20.0. |
| 27 | Configuration parameter dfs.support.append, which is false by default |
