找到hadoop-core-2.7.2.jar路径

Question

I am new to hadoop and I am trying to run a code that use hadoop 1.2.1 version using hadoop 2.7.2 version. This is part of the code:

MR_HADOOPJAR=/usr/local/hadoop/hadoop-1.2.1/hadoop-core-1.2.1.jar
MR_MANIFEST=${rootPath}mp/src/manifest.txt
echo "Compiling mp source code.."
javac -classpath $MR_HADOOPJAR ${rootPath}mp/src/*.java

However, I can not find the hadoop-core-2.7.2.jar?? Any thoughts about the path of hadoop-core-2.7.2.jar??

Answer 1

对于此版本，我们在hadoop中没有hadoop-core jar，但我们有hadoop-mapreduce-client-core-2.7.2.jar

Answer 2

basically you can just

1. locate the 'hadoop-core-2.7.2.jar'

2. using the '-classpath' to include it into your compile process

Obviously the answer already lies in your code
