spark-unsafe_2.10-1.6.2.jar of DStreamTest build path is cross-compiled with an incompatible version

MyEclipse运行spark程序时报错如下：

spark-unsafe_2.10-1.6.2.jar of DStreamTest build path is cross-compiled with an incompatible version of Scala (2.10.0). In case this report is mistaken, this check can be disabled in the compiler preference page.

这类提示scala版本不兼容的问题，可以按如下方法解决

解决方案：   

Windows—>Preferences—>Scala—>Compiler

之后再Compiler界面点击Build manager，取消勾选withVersionClasspathValidator选项
