Answer 1

这是因为依赖的Hadoop ‘jar’ 是使用 JDK 1.7 编译，但是我们在运行时却在 JDK 1.6 环境下运行。所以主要原因是 JDK 版本过低导致。

版本对照关系可以参考：https://en.wikipedia.org/wiki/Java_class_file

Java SE 9 = 53 (0x35 hex)
Java SE 8 = 52 (0x34 hex)
Java SE 7 = 51 (0x33 hex)
Java SE 6.0 = 50 (0x32 hex)
Java SE 5.0 = 49 (0x31 hex)
JDK 1.4 = 48 (0x30 hex)
JDK 1.3 = 47 (0x2F hex)
JDK 1.2 = 46 (0x2E hex)
JDK 1.1 = 45 (0x2D hex)

根据上面的分析把 JDK 版本提升到 JDK 1.7 即可。
