sqoop job 创建报错 Got exception running Sqoop: java.lang.NullPointerException java.lang.NullPointerExce

导致的，我的 sqoop 版本是 1.4.7，不知道新版本会不会包含该 jar，因为我不想更换版本，所以手动下载 java-json.jar 到 ${SQOOP_HOME}/lib 下即可解决该问题。下载地址：http://www.java2s.com/Code/Jar/j/Downloadjavajsonjar.htm。如果上面的地址访问不了，可以关注公众号：huangxy，回复 java-js
