I upgrades Cassandra version from 2.1.11 to 4.0.13, and i see below package has been removed from the Cassandra version 2.2 onwards,

[ERROR] */BloomFilterLookup.java:[132,27] package Murmur3BloomFilter does not exist

v2.1: https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/utils

v2.2: https://github.com/apache/cassandra/tree/cassandra-2.2/src/java/org/apache/cassandra/utils

Am not able to find the alternative package to use at place of Murmur3BloomFilter. Also didn’t find any migration document for upgrading from v2.1 to v4.0.

Could someone help me on this ?
