### What problem does this PR solve? Problem Summary: As this issue describes https://github.com/apache/hudi/issues/12918 While debugging a memory leak issue, I noticed a steady increase in the number of BitCaskDiskMap instances through jmap logs. Using VisualVM, I found that a memory leak may exist in BitCaskDiskMap due to a circular reference.  - The cleanup method is an instance method that implicitly depends on the this pointer - When cleanup is called from shutdownThread, it holds a reference to this - Meanwhile, the DiskMap class holds a reference to shutdownThread  This creates a circular reference: ```text DiskMap (this) -> shutdownThread -> cleanup -> DiskMap (this) ``` ### Release note This pr use a new DiskMap.java to shade the original DiskMap.java to prevent the problem. ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test. Explain why: - [ ] This is a refactor/code format and no logic has been changed. - [ ] Previous test can cover this change. - [ ] No code files have been changed. - [ ] Other reason <!-- Add your reason? --> - Behavior changed: - [ ] No. - [ ] Yes. <!-- Explain the behavior change --> - Does this need documentation? - [ ] No. - [ ] Yes. <!-- Add document PR link here. eg: https://github.com/apache/doris-website/pull/1214 --> ### Check List (For Reviewer who merge this PR) - [ ] Confirm the release note - [ ] Confirm test cases - [ ] Confirm document - [ ] Add branch pick label <!-- Add branch pick label that this PR should merge into --> -- This is an automated message from the Apache Git Service.
