Yibing Shi updated HIVE-15225:
------------------------------
Status: Patch Available (was: Open)
> 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
> Attachments: HIVE-15225.1.patch
>
>
> 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.
