在LINUX 搭建eclipse+hadoop 编译代码出现错误

              hadoop : hadoop-1.2.1 (因为eclipse插件不符合，特意换了以前版本的)
              eclipse : eclipse-jee-SR1-indigo-gtl.tar.gz
              JDK : jdk 1.8
              
              一种错误是图片上的 
              还有一个 显示  ：  Multiple markers at this line    - The type java.util.Map$Entry cannot be resolved. It is indirectly referenced      from required .class files    - The type java.util.Map$Entry cannot be resolved. It is indirectly referenced      from required .class files
