             Summary: LAG function get java.lang.ClassCastException: org.apache.hadoop.hive.common.type.HiveDecimal cannot be cast to org.apache.hadoop.hive.serde2.io.HiveDecimalWritable
                 Key: HIVE-25298
                 URL: https://issues.apache.org/jira/browse/HIVE-25298
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 3.1.2
         Environment: Hive 3.1
            Reporter: wenjun ma


When we try to apply the LAG function with aggregation function (MAX), we got ava.lang.ClassCastException: org.apache.hadoop.hive.common.type.HiveDecimal cannot be cast to org.apache.hadoop.hive.serde2.io.HiveDecimalWritable.

reproduce steps:
 # create table:
create table tbl1 (ACCT_NM string, ACCT_BAL decimal(15,2)) partitioned by (DL_DATA_DT string)
 #  insert sample data:insert into tbl1 values ('acct1', 1000.00, '2020-01-01');

insert into tbl1 values ('acct1', 800.00, '2020-01-02');

 ## Run folowing SQL:   
{code:java}
select
test.ACCT_NM,
test.DL_DATA_DT,
test.MAX_ACCT_BAL,
LAG(test.MAX_ACCT_BAL,1,0) OVER (PARTITION BY test.ACCT_NM ORDER BY test.DL_DATA_DT) AS PREV_USED_AMT
from (
select
tbl1.ACCT_NM as ACCT_NM,
tbl1.DL_DATA_DT as DL_DATA_DT,
max(tbl1.ACCT_BAL) as MAX_ACCT_BAL
from tbl1
group by tbl1.ACCT_NM, tbl1.DL_DATA_DT
) test;
{code}
