Hemanth Yamijala resolved ATLAS-461.
------------------------------------
    Resolution: Invalid

Not an Atlas Issue. Couldn't figure out which project this is as well - Apache Commons?

>                 Key: ATLAS-461
>                 URL: https://issues.apache.org/jira/browse/ATLAS-461
>             Project: Atlas
>          Issue Type: Improvement
>            Reporter: Eric Nelson
>            Priority: Minor
>
> In Apache Commons Math, the dimensions of OpenMapRealMatrix is restricted to numRows * numColumns < Java's Integer.MAX_INT (2,147,483,647). Changing this to be stored as Longs would remove this constraint. 
> I am trying to use a slightly larger 50625 * 50625 sparse matrix but it's failing with
> org.apache.commons.math3.exception.NumberIsTooLargeException: 2,562,890,625 is larger than, or equal to, the maximum (2,147,483,647)
