Subject [jira] [Created] (HIVE-8008) NPE while reading null decimal value
Date Fri, 05 Sep 2014 23:00:30 GMT
Chao created HIVE-8008:
--------------------------

             Summary: NPE while reading null decimal value
                 Key: HIVE-8008
                 URL: https://issues.apache.org/jira/browse/HIVE-8008
             Project: Hive
          Issue Type: Bug
            Reporter: Chao
            Assignee: Chao


Say you have this table {{dec_test}}:
{code}
dec                 	decimal(10,0)       	                    
{code}

If the table has a row that is 9999999999.5, and if we do

{code}
select * from dec_test;
{code}

it will crash with NPE:

{code}
