---------------------------------
Summary: QueryPlan.getJSONValue should code against empty string
values
Key: HIVE-15225
URL: https://issues.apache.org/jira/browse/HIVE-15225
Project: Hive
Issue Type: Bug
Reporter: Yibing Shi
The current {{QueryPlan.getJSONValue}} implementation is as below:
{code}
public String getJSONValue(Object value) {
String v = "null";
if (value != null) {
v = value.toString();
if (v.charAt(0) != '[' && v.charAt(0) != '{') {
v = "\"" + v + "\"";
}
}
return v;
}
{code}
When {{value.toString()}} returns an empty string, a
StringIndexOutOfRangeException would be thrown out when "v.charAt(0)" is
evaluated.
