Hari Sankar Sivarama Subramaniyan commented on HIVE-8115:
---------------------------------------------------------

There are 2 options here :
1. Modify Driver.getResults to throw an exception when the data is invalid.
2. Modify LazyMap.parse() something similar to this:
{code}
        if (lazyKey != null) {
                Object key = lazyKey.getObject();
                if(!keySet.contains(key)) {
                        mapSize++;
                        keySet.add(key);
                } else {
                        keyInited[mapSize] = false;
                }
        } else {

                // Log the error without throwing an exception
        }
{code}

Thanks
