AUse Gzip codec because it supports splittable compression

BUse Snappy codec instead because LZO is not splittable

CDisable compression to allow splitting

DInstall LZO native libraries and use LZO index files for splittability

Step-by-Step Solution

Solution:

Step 1: Understand LZO splittability
LZO files are splittable only if native libs and index files (.index) are present.
Step 2: Identify required setup
Install native libraries and generate index files to enable splitting.
Final Answer:
Install LZO native libraries and use LZO index files for splittability -> Option D
Quick Check:
