过了一遍
温习了一遍, 记下几个数据:
by default, the maximum heap size is set to either 1/4th of the physical memory available to the OS, or to 1 GB
By default, the initial heap size is set to either 1/64th of the physical memory available to the OS
By default, the ratio is set to 2 (the old generation occupies ⅔ of the heap, and the young generation occupies ⅓)
By default, the thread stack size is set to 320 KB or 1024 KB, depending on the platform
涉及Hive,Spark的大量背景知识, 初步理解:Hive是基于MR(包括Spark)之上的类SQL引擎 Spark是一个类MapReduce的计算框架,基于HDFS之上,是Hadoop生态系统中的一员。 文章讲了用Spark作为Hive后端的好处以及它们交互的一些知识。 [x] 阅读 http://www.cloudera.com/content/cloudera/en/developers/home/cloudera-labs/a 软文, 推cloudera的课程?

Java8 还是有很多进步的, 个人的JDK默认已经切换到8了。
