Hi Ravikumar,
that file has in fact been removed in Pentaho Server 8.2.
You should either have a browser cache problem or have a dashboard that makes explicit use of the said module.
For the former, just make sure you clear the browser cache. For the latter, it needs to be solved on a case by case basis; we'd need to see the code that is using the said module to find an alternative.
Cheers,
Duarte
