Work Description: Rutuja123-dos opened a new pull request, #844:
URL: https://github.com/apache/mahout/pull/844
### Purpose of PR
This PR adds a regression test for the async amplitude encoding chunk bounds
issue (#743).
The Problem: When performing amplitude encoding in chunks, the kernel must
respect the specific chunk_len for the offset provided, rather than the full
state_len. Out-of-bounds writes can occur if the bounds are not correctly
constrained.

> The RandomUtils package has a trick for running unit tests repeatably. All
> random generators created with RandomUtils.getRandom() are started with seed
> 0. Unfortunately, all random generators started with
> RandomUtils.getRandom(seed) effectively run from a seed of 0. Thus, code
> which deliberately creates Random objects with seeds does not work correctly
> under unit tests.
> The problem is that the logic in RandomWrapper tests for unit test mode and
> settable seed mode in the wrong order.
