Sharmadha Sainath created ATLAS-2214:
----------------------------------------

             Summary: Search using entity and trait attributes  "!=" and "is not null"  together
and in order in string,boolean tag filter attribute comparison
                 Key: ATLAS-2214
                 URL: https://issues.apache.org/jira/browse/ATLAS-2214
             Project: Atlas
          Issue Type: Bug
          Components:  atlas-core
            Reporter: Sharmadha Sainath
            Priority: Critical
         Attachments: not_equals_and_not_null_tag_filter_exception.txt

1. Created a tag tag1 with attributes of all data types.
2. Fired a basic search with tag1 and following tag filters of type string:
            a)string  != rand
            b)string is not null
POST body 
{code}
{  
   "excludeDeletedEntities":true,
   "entityFilters":null,
   "tagFilters":{  
      "condition":"AND",
      "criterion":[  
         {  
            "attributeName":"string",
            "operator":"neq",
            "attributeValue":"rand"
         },
         {  
            "attributeName":"string",
            "operator":"not_null",
            "attributeValue":""
         }
      ]
   },
   "attributes":null,
   "limit":25,
   "offset":0,
   "typeName":null,
   "classification":"tag1"
}
{code}

The search threw 500 Internal server exception. Attached the stack trace .

Note :
1)This exception is not seen if order is reversed (i.e) , in the order
   a)string is not null
   b)string  != rand 
    In this order , correct results are fetched.

2)For string and boolean data types , this exception is seen. This was not seen with int ,
float, short , double , date , enum .
           
3)Also , this issue is seen only in tag attribute filters and not in type attribute filters.
