Sqoop错误：CLIENT_0004:Unable to find valid Kerberos ticket cache (kinit)

# 背景

今天在使用JavaAPI来连接sqoop1.99.7的时候，遇到了个错误。错误信息如下：

[main] WARN  org.apache.hadoop.util.NativeCodeLoader  - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

问题分析： 从报错信息上看貌似是Authentication认证的一些错误

网上找了查了很多都没发现解决方案。
从官网security Authentication章节也没看到好的解决方案，想要配置Kerberos相关的Authentication，一看太麻烦感觉也不太靠谱 http://sqoop.apache.org/docs/1.99.7/security/AuthenticationAndAuthorization.html (opens new window)
