> In bulk writer after writing SSTables, written data to SSTables is read back
> again to perform validations before shipping the files to the Cassandra
> instances. The logic to validate the SSTables assumes
> {{{}Murmur3Partitioner{}}}. This validation fails however when a bulk writer
> job is running against a cluster using the {{RandomPartitioner}} with the
> following stacktrace:
> {code}
> java.lang.RuntimeException: java.lang.IllegalStateException: Partitioner in
> ValidationMetadata does not match TableMetaData:
