What is 152³305746 - hadoop

Question

I am getting 152³305746 as some bad data in my input file. I am trying to filter it, but have been unsuccessful in telling hive on how to detect it and filter. I am not even sure what data type it is. I am expecting bigint values instead of what i see here.
I have tried the below things and their various combinations which did not help skip the few bad records i have in my input:
1)
CAST(mycol AS string) RLIKE "^[0-9]+$"
2)
mycol < 2147483647
3)
CREATE TEMPORARY MACRO isNumber(s string) CAST(s as BIGINT) IS NOT NULL;
4)
isNumber(mycol) != false
5)
SET mapreduce.map.skip.maxrecords = 100000000;
None of the above approaches worked. Hive fails with the following error:
