## What changes were proposed in this pull request? Currently, the Ozone File System (OzoneFileSystem) client's implementation of `org.apache.hadoop.fs.LocatedFileStatus.getBlockLocations()` returns **null** when the file size is **0 bytes**. This behavior is inconsistent with the **HDFS File System client**, which correctly returns an **empty `BlockLocation[]` array** for zero-byte files, as per the standard Hadoop FileSystem API contract for files with no blocks. **This commit addresses the compatibility issue by modifying `OzoneFileSystem` to return an empty `BlockLocation[]` array when:** 1. The file size is 0. 2. The internal block list is empty (which is true for 0-byte files). This change ensures better interoperability and seamless compatibility for applications relying on the expected behavior of the Hadoop FileSystem API. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-14161 ## How was this patch tested? add unit tests -- This is an automated message from the Apache Git Service.
