Hadoop MapReduce InputFormat已弃用?(Hadoop MapReduce InputFormat Deprecated?)

我需要为Hadoop MapReduce应用程序实现自定义(服务)输入源。 我google'd和SO'd,发现一种方式继续是实现一个自定义InputFormat。 那是对的吗?

显然根据http://hadoop.apache.org/common/docs/r0.20.2/api/org/apache/hadoop/mapred/InputFormat.html InputFormat的方法getRecordReader()和getSplits()已被弃用。 什么是替代品?

Hadoop's WordCount example still uses the same...

最满意答案

问题中的代码将红色文本样式设置为titleTextStyle并在创建轴标签时使用labelTextStyle 。 这些文本样式是独立的,但如果您愿意,可以为两者使用相同的样式。


The code in the question sets the red text style to the titleTextStyle and uses the labelTextStyle when creating axis labels. These text styles are independent although you can use the same style for both if you want.
