resolvent : First locate your map<?,?> or array<?> Type of error reporting location ,( Positioning method : One taste map perhaps array The value of is manually set to null, Try the first half , Just set the next half of the data to null Try this method in turn ,)
second : Find the corresponding position , I worry about null values
Column inserts an empty set or map in key by null In the case of , This will trigger the error ,

Later, it was found that there had been official discussions ：https://issues.apache.org/jira/browse/HIVE-11625
There is no version that fixes this problem !!!
