> [{{com.tdunning}}|https://github.com/tdunning/open-json/blob/rc1.8/src/main/java/org/json/JSONObject.java#L141-L155]
> as part of the HIVE libs (if one is reusing the {{HADOOP_CLASSPATH}}) in the
> classpath. but I think we can better have a checker of {{null}} in
> {{SqoopJsonUtil.getJsonStringforMap(Map<String, String> map)}} before calling
> {{JSONObject pathPartMap = new JSONObject(map);}}
> Reporting this bug and the right behavior need to be decided by the assignee.
