FAQ:

1. 在创建job时如果遇到类似NoClassDefFoundError: org/json/JSONObject的错误，详细如下

Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONObject
at org.apache.sqoop.util.SqoopJsonUtil.getJsonStringforMap(SqoopJsonUtil.java:43)
at org.apache.sqoop.SqoopOptions.writeProperties(SqoopOptions.java:785)
at org.apache.sqoop.metastore.hsqldb.HsqldbJobStorage.createInternal(HsqldbJobStorage.java:399)
......

原因：sqoop缺少java-json.jar包.

解决：

这是因为sqoop缺少java-json.jar包.

下载java-json.jar包：

把java-json.jar添加到../sqoop/lib目录：

cp java-json.jar  /sqoop/lib
