Extra ZEROS getting generated in Target table

[Lunagariya, Dhaval]

Hey folks,

I am executing INSERT INTO SELECT hive query through oozie workflow. Below are 
the details. Extra zeros are getting generated in target table(parquet_table). 
Can anyone help me to identify the issue.

Ex.

Value of COLUMN_SAMPLE in source table(tab1) : 1
Value of COLUMN_SAMPLE in destination table(parquet_table) :  
1000000000000000000


Avro column:
"name":"COLUMN_SAMPLE","type":["null",{"type":"bytes","logicalType":"decimal","precision":"38","scale":"18"}]

Select Query(insert.sql):

insert into table parquet_table select * from default.tab1;
