Sort check failed

REASON:
In the process of investigation it became clear the following: when we store data in pig, we assign them the data type. This leads to the fact that the file size changed (probably because of the removal of extra delimiters). As a result of subsequent actions sorting is carried out already with the changed data (different file size). In bash (on Cent OS, Ubuntu and Mac OS), in turn, we do not have the ability to work with data types, and when we perform any sorting, we make them with the same "raw data". As a result, the check at the end of the test is incorrect because the files that are compared have different size.
We also have different results during sorting on Cent OS/Ubuntu and Mac OS. All these inaccuracies lead to failure in sort check.
