Hadoop 終於要進入JDK 7的時代了




離上一篇文章 何時Hadoop 才能正式轉換至 JDK7 ? (2013.4.25)又快過了一年了,讓我們繼續來追蹤更新的進度吧,根據 HadoopJavaVersions wiki 最後一次更新日期 (2013-10-25 17:10:21 by JunpingDu),Hadoop 已經正式可以使用在JDK 7 上面了,不管是Hortonwork 和 Cloudera 都已經有正式支援與驗證的版本。

其實現在才發現已經有點Lag了.....只是今天剛好看到Cloudstack 也在討論是否要換到JDK7 - [Proposal] Switch to Java 7,才赫然發現wiki已經更新了....Anyway...讓我們拍拍手進入JDK7 的時代~XD



(不過....要換JDK7 代表Hadoop 也要升級到2.x唷~:P )
