hadoop 2.7.3 与 hadoop 2.6.5 之间有什么区别

What is difference between hadoop 2.7.3 vs hadoop 2.6.5

我最近遇到了 Hadoop 版本,在此我注意到,2.6.5 和 2.7.3 都是并行开发的,simultaneous.If可能有人请告诉我它们之间的区别。

08 October, 2016: Release 2.6.5 available A point release for the 2.6 line. Please see the Hadoop 2.6.5 Release Notes for the list of 79 critical bug fixes and since the previous release 2.6.4.

25 August, 2016: Release 2.7.3 available A point release for the 2.7 line. Please see the Hadoop 2.7.3 Release Notes for the list of 221 bug fixes and patches since the previous release 2.7.2.

http://hadoop.apache.org/releases.html 解释 2.6 和 2.7 版本之间的区别:

21 April 2015: Release 2.7.0 available

Apache Hadoop 2.7.0 contains a number of significant enhancements. A few of them are noted below.

    IMPORTANT notes
        This release drops support for JDK6 runtime and works with JDK 7+ only. 

所以区别在于 2.7 是为 JDK 7+ 引入的,但是 2.6 继续发布以支持 JDK6 位用户。

从同一个 link 中,您可以看到 2.7 比 2.6 树有更多的错误修复。
