RANGER-5125: Missing accessResult column value in ORC File Logging

[zbaranow]

What changes were proposed in this pull request?

• Fixed an issue where short values (e.g., accessResult field) were not correctly converted to strings before being written to ORC.
• Modified castStringObject(Object object) to properly handle Short values by converting them to strings.

Why is this needed?

• Previously, short values were missing from the ORC output because they were not handled in castStringObject(), leading to incorrect (empty) values in the ORC file.
• This fix ensures that short values are correctly converted to strings before being stored in ORC.

How was this patch tested?

• Manual testing by running the main() method from OrcUtils.java.
• Verified that the accessResult column in the generated ORC file now contains the correct values instead of being empty.
