Spark 版本及發佈 |

2011 年 AMPLab 開始開發 Spark 的高階元件，例如 Shark
1
（Hive on Spark）和 Spark
串流元件。這些元件有時候被稱為柏克萊資料分析堆（Berkeley Data Analytics Stack,
BDAS）（

）。
Spark 專案在 2010 年 3 月首次開放原始碼，必且在 2013 年 6 月提交至 Apache 軟體基金
會。現在已是 Apache 的頂級專案。
Spark 版本及發佈
Spark 自建立起即成為一個非常活耀的專案並擁有廣大的社群。貢獻者人數也隨著每次
版本的發佈而增加。Spark1.0 版即擁有超過 100 位貢獻者。隨著專案活耀程度的快速成
長，社群也持續地定期發佈 Spark 的更新版本。Spark1.0 版在 2014 年 5 月發佈。這本書
專注於 Spark1.1.0 及其之後版本（Spark1.3 版）的功能，雖然多數的觀念與範例可以在
更早之前的版本中正常運作。

分散式的資料集。請記住，Spark 並不需要 Hadoop；它只是支援了 Hadoop API 所實現
的檔案系統。Spark
