Fix: ml/engine/utils/FileUtils casts long file length to int incorrectly

[maxlepikhin]

Description

"(int) file.length()" makes length negative for file sizes greater than 2GB (but less than 4GB). This results in function returning empty list of chunks and model registration task being stuck in CREATED state.

The fix is to use longs when splitting model zip file. Tested locally that updated opensearch-ml-algorithms jar fixes the problem.

From 11/17/22 (bfb0748): all releases it seems. It'd be great if somebody from the maintainers can help the tests pass, are they flaky?

[mingshl]

It's a flaky test.

Created the issue to track it.

Approved.
