Incompatibility in LZ4 dependencies

There is an incompatibility in LZ4 dependencies being imported in spark 2.3.0

org.apache.spark:spark-sql-kafka-0-10_2.11:2.3.0 imports org.apache.kafka:kafka-clients:0.11.0.0, which imports net.jpountz.lz4:lz4:1.3.0
OTOH, org.apache.spark:spark-core_2.11:2.3.0 imports org.lz4:lz4-java:1.4.0

These jars have the same classes. Which is the right one to use? I see that the jars folder has lz4-java:1.4.0. Is that the right dependency?
