> Comparing bigints and varchars or chars may result to wrong result, for example:
> CREATE TABLE test_a (appid1 varchar(256), appid2 char(20));
> INSERT INTO test_a VALUES ('2882303761517473127', '2882303761517473127'), ('2882303761517473276','2882303761517473276');
> SET hive.strict.checks.type.safety=false;
> SELECT appid1 FROM test_a WHERE appid1 = 2882303761517473127;
> SELECT appid2 FROM test_a WHERE appid2 = 2882303761517473127;
> Both queries will output the row: ('2882303761517473276','2882303761517473276')
