### Purpose of this pull request
This pull request addresses two issues identified in the HDFS checkpoint
storage code:
- Fix Double-Checked Locking: Ensures proper thread safety and lazy
initialization.
- Improve Logging: Enhances log messages for better debugging and clarity.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
This patch primarily involves minor changes to logging and the addition of
the volatile keyword to a field. Given the nature of these changes, no new test
cases were added. The existing test suite covers the functionality of the
HdfsStorage class, and these changes do not introduce new logic that requires
additional testing.
The changes made are:
Logging Improvements: Enhanced log messages for better clarity and debugging.
Volatile Keyword: Added the volatile keyword to ensure visibility of changes
to the fs field across threads.
These modifications are unlikely to affect the existing behavior, and thus,
the existing test cases are sufficient to validate the changes.
