A Brief introductionDebugging HADOOP2 code on eclipse under Windows, So we configured the Hadoop-eclipse-plugin-2.6.0.jar plugin under Windows Eclipse, and there was a series of problems running the Hadoop code, and it took days to finally run the code. Next we look at the problem and how to solve it, providing the same problems as I have encountered as a reference.The Wordcount.java statistics code for HADOOP2 is as follows: packageorg.apache.hadoop.examples;importjava.io.ioexception;importjava
